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){

}

```

Define operators. Explain types of operators.

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.

Define data types. Explain different data types used in C.

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.

Define control structure. Explain different types of control structure.

Control Structures are 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.

Define functions. Write the advantages of function with program example.

A function is 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 the main() function.

Here are several...

Differentiate between structure and union.

Structures in C is a user-defined data type available in C that allows to combining of data items of different kinds. Structures are used to represent a record. 

Defining a structure: To define a structure, you must use the struct statement. The struct statement defines a new data type, with more than or equal to one member. The format of the struct statement is as follows:

struct [structure name] { member definition; member definition; ... member definition;...
