#include <stdio.h>
int main() {
    int firstNum, secondNum, sumEven = 0, sumSqaureEven = 0;
    printf("Please enter the firstNum and secondNum\n");
    scanf("%d %d", &firstNum, &secondNum);
    if ( firstNum> secondNum ) {
        printf("First number should be less than second\n");
        return 0;
    }
    printf("Even numbers:\n");
    for ( int i = firstNum; i <= secondNum; i++ ) {
        if ( i % 2 == 0 ) {
            sumEven += i;
        } else {
            printf("%d ", i);
            sumSqaureEven += i*i;
        }
    }
    printf("\nSum of all even numbers is %d\n", sumEven);
    for ( int i = firstNum; i <= secondNum; i++ ) {
        printf("Number : %d Square version:%d\n", i, i*i);
    }
    printf("Sum of all  sqaures of odd numbers is %d\n", sumSqaureEven);
    return 0;
}
