C Program for loop: "Find Sum of Odd Number between 1 to n number using for loop" with output

 #include <stdio.h>

int main() { int n, sum = 0; printf("Enter a positive integer (n): "); scanf("%d", &n); if (n < 1) { printf("Please enter a positive integer.\n"); return 1; } for (int i = 1; i <= n; i++) { if (i % 2 != 0) { sum += i; } } printf("Sum of odd numbers between 1 and %d is: %d\n", n, sum); return 0; }

Enter a positive integer (n): 10 Sum of odd numbers between 1 and 10 is: 25
