Control Loop programs
This section contains example programs demonstrating the loop
construction.
Program using char data type and simple for loop:
#include /* library header */
main()
{
char ch;
for (ch = 'A' ; ch <= 'z' ; ch++) printf("%c\n" , ch);
}
This program demonstrates the while loop.
#include
main()
{
int lower , upper , step;
float fahr , celsius;
lower = 0 ;
upper = 300;
step = 20 ;
fahr = lower;
while ( fahr <= upper ) {
celsius = (5.0 / 9.0) * (fahr - 32.0);
printf("%4.0f %6.1f\n" , fahr , celsius);
fahr = fahr + step;
}
}
This program uses do-while and for loop constructions and standard library
mathematical functions.
#include
#include
main()
{
int i , j , k;
double a=10.0 , b=.0;
do {
printf("%f\n" , pow(a,b)); /* standard function */
b++;
} while (b<100);
i = 2;
for (j=2 ; j<100 ; j=j+2) {
i=i*j ;
printf("%d\n" , i);
}
}

nice programs collection in which he explained for, while & do...while loop. we can also create a infinite loop for while, for & do...while loop like this.
For Infinite loop
for(;;)
printf("hello");
this will print hello infinite times using for loop.
while Infinite loop
int a=1;
while(a<10)
{
printf("hello");
}
this will print hello infinite times using while loop.
do...while Infinite loop
int a=1
do
{
printf("hello");
}
while(a<10)
this will print hello infinite times using do...while loop
