Question

How do I assign a variable to a random integer in c++?

Answer 1

#include <time.h> int main() { int randomnumber ; int max; srand( time(NULL) ); scanf("Enter total number of students %d",&max); randomnumber=rand()% 30; printf("This is your random number\n %d",randomnumber); getchar(); return 0; }

Thank You, here is what i did, run this and see if you can improve anything.

#include <iostream>
#include <time.h>
#include <stdlib.h>

int main()
{
    int i;
    
    for(;;)
    {
        srand((unsigned int)time(NULL));
        int x=rand()%10;
    
        std::cout<<"I'm thinking of a number between 1 and 10"<<std::endl;
    
        int q;
        std::cout<<"Is it: ";
        std::cin>>q;
    
        if(x==q)
        {
            std::cout<<"Correct"<<std::endl;
        }
    
        else
        {
            std::cout<<"Sorry, the number was "<<x<<std::endl;
        }
