==a while loop nested in for loop==

<source lang="cpp">

#include <stdio.h>
void main()
{
long sum = 1L;
int i = 1; /* Outer loop control variable */
int j = 1; /* Inner loop control variable */
int count = 10; /* Number of sums to be calculated */

for( i = 1 ; i <= count ; i++ )
{
sum = 1L; /* Initialize sum for the inner loop */
j=1; /* Initialize integer to be added */
printf("\n1");
/* Calculate sum of integers from 1 to i */
while(j < i)
{
sum += ++j;
printf("+%d", j); /* Output +j on the same line */
}
printf(" = %ld\n", sum); /* Output = sum */
}
}

</source>

==Use getchar inside while loop==

<source lang="cpp">

#include <stdio.h>
#include <conio.h>
int main(void)
{
char ch;
ch = getchar();
while(ch!="e")
ch = getchar();
printf("Found the e.");
return 0;
}

</source>

==While loop to print char==

<source lang="cpp">
#include <stdio.h>
int main() {
char ch;
ch = "a";
while ( ch <= "z" )
printf ( "%c", ch++ );

printf ( "\n" );
}

</source>

==While to sum integers==

<source lang="cpp">

#include <stdio.h>
void main()
{
long sum = 0L;
int i = 1; /* Indexes through the integers */
int count = 10; /* The count of integers to be summed */

/* Sum the integers from 1 to count */
while(i <= count)
sum += i++;
printf("Total of the first %d numbers is %ld\n", count, sum);
}

</source>
