The if statement controls conditional branching.The body of an if statement is executed if the value of the expression is nonzero.The if statement allows you to control if a program enters a section of code or nor based on whether a given condition is true or false.One of the important function of the if statement is that it allows the program to select an action based upon the user's input.For example we can check user entered password by using if statement,and decide whether a user is allowed access to the program.

How Use Loops in C-'DO WHILE' Loops
'DO WHILE' loops are useful for things that want to loop at least once.The syntax is:
do
{
Code to execute
}while(condition);
Example:
#include<stdio.h>
int main()
{
int x;
x=0;
do
{/*"Hello World!" is printed at least one time even though the condition is false*/
printf("Hello World!");
}
while(x!=0);
getchar();
}
Notice that the condition is tested at the end of the block instead of beginning ,so the block will be executed at least once.If the condition is true,we jump back to the beginning of the block and execute it again.A DO WHILE loop is almost the same ...

How Use Loops in C-'While' Loops
WHILE loops are very simple and the syntax is:
while(condition)
{
Code to execute while the condition is true
}
The true represent a boolean expression which could be while(x==1) or while(x!=7),x does not equal to 7.It can be any combination of boolean statements that are legal.Even, while(x==5||y==7) which says execute the code while x equal to 5 or y equal to 7.
Example:
To print numbers up to 10:
#include<stdio.h>
int main()
{
int x=0; /*Don't forget to declare variables*/
while(x<10) /*while x less than 10*/
{
printf("%d",x);
x++; /*Update x ...
How Use Loops in C-'FOR' Loops
Loops are used to repeat a block of code.Loops are one of the most basic but useful task in programming.We can simply produce extremely complex out put using loops.A loops let you write a very simple statement to produce a significantly greater result simply by repetition.
FOR LOOPS:
FOR loops are the most useful one.The syntax of FOR loops:
for(variable initialization; condition; variable update)
{
code to execute while the condition is true
}
Example:
To print numbers upto 10:
#include<stdio.h>
int main()
{
int x;
