Question

(c++) (codeblocks)

Write a program that contains a value-returning function that returns a value to be displayed in main() with the function call. No values are passed to the function. The function body should be written to generate a random number from 1-10 as its return value. Display with the call to function in main():

The function returned the value of <return value> when it was called in main.

Answer 1

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
int getRandNum() {
srand (time(NULL));
return rand() % 10 + 1;
}
int main(){
cout<<"Random number is "<<getRandNum()<<endl;
}

Output:

sh-4.2$ g++ -o main *.cpp                                                                                                                                                                                                                                              

sh-4.2$ main                                                                                                                                                                                                                                                           

Random number is 8
