while loop is the Entry control loop in C language

Syntax-

}
Example-

}

i=10;
while(i>0)
{
i--;
}


program-

#include< stdio.h>
int main()
{
int i;
printf("Before For Loop\n");
i=0;
while(i< 10)
{
printf("Inside loop i=%d\n",i);
i++;
}
printf("After Loop");
}


output-

Before For Loop
Inside Loop i=0
Inside Loop i=1
Inside Loop i=2
Inside Loop i=3
Inside Loop i=4
Inside Loop i=5
Inside Loop i=6
Inside Loop i=7
Inside Loop i=8
Inside Loop i=9
After Loop

-In this program, we start with i=0 then run the while loop 10 times.
