Here, in C programming \n is an escape character that helps to create a new line whereas %d is a format specifier that allows to specify only Integer values.

A programming language is the language used by programmers to develop software programs, scripts, or other sets of instructions for computers to execute.

A programming language can be divided into 2 types:

1. Low-level language
2. High-level language

1) Low-Level Languages (LLL)

Alow-level programming languageis aprogramming languagethat provides little or noabstractionfrom a computer'sinstruction set architecture—commands or functions in the language map that are structurally similar to processor's...

Language translator is a program which is used to translate instructions that are written in source code to object code i.e. from high-level language or assembly language into machine language.

Or,

Language translators allowcomputer programmers to write sets of instructions in specific programming languages which are then converted by the language translator into machine code.

There are 3 types of language translators. They are:

1. Assembler:
   Assembler is the language translator designed to...

There may be several errors inside a program which stops program from being executed or giving the desired result known as a bug. This type of error in a program may arise by not following proper rules given by the programming language, due to poor problem analysis or maybe due to hardware failure.

The different types of errors are:

1. Syntax error:
   
   the error which may arise due to not following proper rules or format given by the programming language. Every programming language have their own...

An algorithm is defined as a finite sequence of explicit instructions that produces an output with the set of input values. The steps in the algorithm are never ambiguous. It terminates after a finite number of steps.Algorithms can have repetitions and logical decisions until a specific task is completed. Algorithms are not computer programs. They cannot be executed by the computer.

Looping isthe process of continually repeating asequence of instructions until a certain condition specified is reached.

The types of loops in C programming languages are:

1) While Loop

. In while loop, a condition is evaluated before processing a body of the loop. If a condition is true then and only then the body of a loop is executed. After the body of a loop is executed then control again goes back at the beginning, and the condition is checked if it is true, the same process is executed...

C program was developed by Dennis Ritchie, originally for UNIX operating system on the DEC PDP-II.

The advantages of C Programming Language are:

1. C is general purpose programming language. You can generate different kind of software such as billing system, games, utilities, word processor, etc.
2. C is the structured programming language. It uses structured statements such as while, for, etc.
3. C is a standardized programming language. For example ANSI (American National Standards Institute) C is a standard programming language.
4. The C language can run in any computer system. It is system...

The features of C programming Language are:

1. Procedural Language:
   In a procedural language like C step by step predefined instructions are carried out. C program may contain more than one function to perform a particular task. New people to programming will think that this is the only way a particular programming language works. There are other programming paradigms as well in the programming world. Most of the commonly used paradigm is an object-oriented programming language.

2. Fast and...

Compiling is the transformation from Source Code (human readable) into machine / object code (computer executable).It is done with the help of the compiler.

The following are the stages of compilation:

• Preprocessor
• Compilation
• Assembling
• Linking

IF STATEMENTSSWITCH CASE

If statement is used to select among two alternatives of 'True' i.e. condition is fulfilledand 'False' i.e. condition is not fulfilled.	The switch statement is used to select among multiple alternatives.
It is a decision making control statement.	It is a selection statement.
The if statement in C, makes sectionsbased on a single true or false condition.	Switch case offers multiple choice for selection of the statements or we can switch case.
It...

The following is a program toinput a number and print if it is positive or not:

#include <stdio.h> int main() { double num; printf("Enter a number: "); scanf("%lf", &num); if (num <= 0.0) { if (num == 0.0) printf("You entered 0."); else printf("You entered a negative number."); } else printf("You entered a positive number."); return 0; }

Or,

#include <stdio.h> int main() { double num; printf("Enter a number: "); scanf("%lf", &num); if (num < 0.0) printf("You entered a...

The following is a C program to input day of a week and print “Holiday” if it is Saturday.

#include <stdio.h>

#include <string.h>
void main() { int week; /* Input week from user */ printf("Enter the day of the week: "); scanf("%d", &a);

char b[8] = "saturday";

if(strcmp(a,b) == 0) { printf("Holiday!!"); }

getch();

}

The following is a C program toinput any 3 numbers and display the largest one:

#include<stdio.h>
int main() { double n1, n2, n3; printf("Enter three numbers: "); scanf("%lf %lf %lf", &n1, &n2, &n3); if (n1 >= n2 && n1 >= n3) printf("%.2lf is the largest number.", n1); else if (n2 >= n1 && n2 >= n3) printf("%.2lf is the largest number.", n2); else printf("%.2lf is the largest number.", n3); return 0; }

The following is a C program to input any number and display its factor.:

#include <stdio.h> int main() { int num, i; printf("Enter a positive integer: "); scanf("%d", &num); printf("Factors of %d are: ", num); for (i = 1; i <= num; ++i) { if (num % i == 0) { printf("%d ", i); } } return 0; }

The following is the source codeto input any number and display its factorial:

#include <stdio.h>

#include <conio.h>

int main()

{

int a, i, factorial;

factorial = 1;

printf("Input any number: ");

scanf("%d", &a);

if (a==0 || a==1) {

printf("The factorial is 1");

} else if (a<0) {

for (i=a; i<0; ++i) {

factorial *= i;

}

} else {

for (i=a; i>0; --i) {

factorial *= i;

}

}

printf("The factorial of %d is %d.", a, factorial);

}

Program to input any number and display number of odd numbers in it;

#include<stdio.h>

#include<stdlib.h>

#include<conio.h>

#include<string.h>

int main() {

int i, number, num1, num2=0, num3, num4 =0, rem, rem1, rem2, rev = 0;

printf("Enter your number ==> ");

scanf("%d", &number);

num1 = number;

while(num1 != 0) {

rem = num1%10;

rem1 = rem%2;

if (rem1 != 0) {

num2 = num2*10 + rem;

}

num1 /= 10;

}

num3 = num2;

while (num2 != 0) {

#include<string.h>

int main() {

int i, number, num1, num2=0;

char str1[50];

num1 = number;

for(i=2; i<=20; i+=2) {

printf("%d", i);

printf(", ");

}

return 0;

}

#include<stdio.h>

#include<conio.h>

#include<string.h>

int main() {

int i, nextTerm;

int t1 = 2, t2 = 2;

nextTerm = t1+t2;

printf("%d, %d, ", t1, t2);

for (i = 3; i <= 10; ++i) {

printf("%d, ", nextTerm);

t1 = t2;

t2 = nextTerm;

nextTerm = t1 + t2;

#include<stdio.h>#include<conio.h>




int main(){int a[50],i,n,large,small;printf("How many elements:");scanf("%d",&n);printf("Enter the Array:");for(i=0;i<n;++i)scanf("%d",&a[i]);large=small=a[0];for(i=1;i<n;++i){if(a[i]>large)large=a[i];if(a[i]<small)small=a[i];}printf("The largest element is %d",large);printf("\nThe smallest element is %d",small);return 0;}

Simply put:

Thescanf()function reads the sequence of characters until it encounterswhitespace(space, newline, tab, etc.).

For reading a string value with spaces, we can use either gets() or fgets() in C programming language.

Here, we will see what is the difference between gets() and fgets().

fgets()

It reads a line from the specified stream and stores it into the string pointed to by str. It stops when either (n-1) characters are read, the newline character is read, or the end-of-file is...
