Question

1. Write a for loop that prints the sum of all positive even integers less than 200. Assume that variables i and sum are already declared.

2. Write a while loop that prints the sum of all positive odd integers less than 100. Assume that variables i and sum are already declared.

3. Write a do-while loop that prints the sum of all positive multiples of 3 less than or equal to 150. Assume that variables i and sum are already declared.

Answer 1

$\color{blue}\underline{1:}$

for (i = 0; i < 200; i += 2) {
    sum += i;
}
printf("%d\n", sum);

$\color{blue}\underline{2:}$

i = 1;
while (i < 100) {
    sum += i;
    i += 2;
}
printf("%d\n", sum);

$\color{blue}\underline{3:}$

i = 0;
do {
    sum += i;
    i += 3;
} while (i <= 150);
printf("%d\n", sum);
