| C++/C Solution (Sum or Product) |
Question :
Write a program that asks the user for a number N and a choice C. And then give them the possibility to choose between computing the sum and computing the product of all integers in the range 1 to N (both inclusive).
If C is equal to -
- then print the sum
- then print the product
*Any other number, then print '-1' (without the quotes)*
Input format :
Line 1 : Integer N
Line 2 : Choice C
Output Format :
Sum or product according to user's choice
Constraints :
1 <= N <= 12
Sample Input 1 :
10
1
Sample Output 1 :
55
Sample Input 2 :
10
2
Sample Output 2 :
3628800
Sample Input 3 :
10
4
Sample Output 3 :
-1
Solution Code
#include <iostream>
using namespace std;
int main () {
int sum = 0, prod = 1;
int num;
// cout << "Enter a Number ?" << endl;
cin >> num;
int choice;
// cout << "Do you want to compute the sum or product?" << endl;
cin >> choice;
if ( choice == 1 ) {
for ( int i = 1; i <= num; i++) {
sum += i;
}
cout << sum << endl;
}
else if( choice == 2 ) {
for ( int i = 1; i <= num; i++) {
prod = prod * i;
}
cout << prod << endl;
}
else {
cout << -1 << endl;
}
}
