C program for Sum of n number using if else statements?

Answer 1

// Why do you need if/else statements?

int main()

{

int numbers[] = {1, 2, 3, 4, 5, 6}; // and so on

int i;

int sum = 0;

for(i = 0; i < sizeof (numbers)/sizeof(int); i++)

sum += i;

return sum;

}

Answer 2

#include main() /* program which introduces keyboard input */

{

inti = 1;

int inumber = 0;

int itotal = 0;

do

{

printf("Type in a number greater than zeroor zero to end program\n");

scanf("%d", &inumber);

printf("The number you typed was %d\n", inumber);

if (inumber 1);

printf("You ended the program, hit any key to continue\n");
