Write a C program to generate Fibonacci series. [0,1,1,2, 3, 5, 8...10th term]

Operators can be defined as basic symbols that help us work on logical and mathematical operations.Operators in C and C++, are tools or symbols that are used to perform mathematical operations concerning arithmetic, logical, conditional and, bitwise operations.

1. ArithmeticOperators

It includes basic arithmetic operations like addition, subtraction, multiplication, division, modulus operations, increment, and decrement.

The Arithmetic Operators in C and C++ include:

1. + (Addition)– This operator...

A data type specifies the type of data that a variable can store such as integer, floating, character, etc.

There are the following data types in C language.

TypesData Types

Basic Data Type	int, char, float, double
Derived Data Type	array, pointer, structure, union
Enumeration Data Type	enum
Void Data Type	void

Basic Data Types

The basic data types are integer-based and floating-point based. C language supports both signed and unsigned literals.

The memory size of the basic data types...

Control Structuresare just a way to specify flow of control in programs. Any algorithm or program can be more clear and understood if they use self-contained modules called as logic or control structures. It basically analyzes and chooses in which direction a program flows based on certain parameters or conditions.

1. Sequential Logic (Sequential Flow)

   Sequential logic as the name suggests follows a serial or sequential flow in which the flow depends on the series of instructions given to the...

For loop is used when number of iteration is known. eg :

``` for (int i=0;i<n;i++){

}

```

Incase if while loop , it runs till the condition is true. eg:

```

while(n>0){

}

```

Afunctionis basically a block of statements that performs a particular task. Suppose a task needs to be performed continuously on many data at different points of time, like one at the beginning of the program and one at the end of the program, so instead of writing the same piece of code twice, a person can simply write it in a function and call it twice. And after the execution of any function block, the control always comes back to themain()function.

Here are several advantages of using...

#include<stdio.h>

void check(int);

int main()

{

int n;

printf("enter the number ");

scanf("%d",&n);

check(n);

}

void check(int n)

{

if(n%2==0)

{

printf("%d is even number",n);

}

else{

printf("%d is not even number",n);

}

}

Output:

enter the number 7

7 is not even number

Note cs50 library is used here.

#include<stdio.h>#include<cs50.h>
int main(void){ int n = get_int("Enter any number: "); if (n % 5 == 0 && n % 7 == 0) { printf("It is divisible by both 5 and 7.\n"); } else if (n % 5 == 0 && n % 7 != 0) { printf("It is divisible by 5 but not by 7.\n"); } else if (n % 5 != 0 && n % 7 == 0) { printf("It is divisble by 7 but not by 5.\n"); } else { printf("It is not divisble by both 7 and 5.\n"); }}

Recursion in C is a process where a function calls itself as a subroutine in order to solve a particular problem. In this process, the function repeats itself with different arguments until a specific termination condition.

A function in C is a block of code that performs a specific task. It is a reusable code module that can be called by other parts of a program. Functions help in modular programming, where complex programs are divided into smaller, simpler parts that can be easily understood and maintained.
