Explain the using a while loop.

Question

guys I am not able to understand while loop
so, please explain me in simple way.

Answer 1

while ()
{
//body of loop
}

it is a common syntax of while loop

if you want pergmform any operation in multiple times so you can use while loop

suppose you want print 0 to 10 numbers, I so you will write while loop like that

int a=0;
while (a<=10)
{
a++;
printf ("%d",a);
}

and the output is

0
1
2
3
4
5
6
7
8
9
10

Answer 2

syntax of while loop is:
while(condition)
{
//operations
//output statements
//increment or decrement statements
}

it performs operation many times and print output of each operation still the condition becomes false.
example-
int count= 1;

while (count < 8) {
printf("Count = %d\n",count);
//output statement
count++;//increment statement
}

return 0;
}
output:
count=1
count=2
cont=3
count=4
count=5
count=6
count=7
