APL to add 10 natural numbers and store the result in $500
Answers
Sum of Natural Numbers Using for Loop
#include <stdio.h>
int main() {
int n, i, sum = 0;
printf("Enter a positive integer: ");
scanf("%d", &n);
for (i = 1; i <= n; ++i) {
sum += i;
}
printf("Sum = %d", sum);
return 0;
}
The above program takes input from the user and stores it in the variable n. Then, for loop is used to calculate the sum up to n.
Sum of Natural Numbers Using while Loop
#include <stdio.h>
int main() {
int n, i, sum = 0;
printf("Enter a positive integer: ");
scanf("%d", &n);
i = 1;
while (i <= n) {
sum += i;
++i;
}
printf("Sum = %d", sum);
return 0;
}
Output
Enter a positive integer: 100
Sum = 5050
In both programs, the loop is iterated n number of times. And, in each iteration, the value of i is added to sum and i is incremented by 1.
