My program works, but I would like for the numbers to be random instead of 1-12...

I know I have to do srand and I want the numbers to at least go to 50, so like a rand()%50, but I'm not really sure where to plug it in, if thats right.

thanks for all your help

here is my code:

``````#include <ctime>
#include <iomanip>
#include <string>
#include <fstream>
#include <iostream>
using namespace std;

int main()
{
int product;
int sum;
int correct = 0;
int wrong = 0;

srand(time(0));

do {
cout << setw( 55 ) << "Childrens Math Quiz Game!!!" << endl;
cout << setw( 47 ) << "Author: Preston" << endl << endl;
cout << setw( 49 ) << "**********Menu**********" << endl;
cout << setw( 50 ) << " Multiplacation " << endl;
cout << setw( 44 ) << " Addition " << endl;
cout << setw( 47 ) << " Subtraction " << endl;
cout << setw( 40 ) << " Exit " << endl << endl;

switch ( menu )
{
case 1:
for ( int i = 1; i <= 12; i++ )

for( int j = 0; j <= 12; j++ ){

cout << "What is " << i << " X " << j << " = ";
product = i * j;

if( answer == product ) {
cout <<"Good Job!!!!!" << endl << endl;
correct++;
}
else {
cout << "Sorry " << i <<" X " << j << " = " << product<< endl << endl;
wrong++;
}
}

cout << "You got " << correct <<" right and " << wrong << " wrong"<< endl<< endl;
cin.get();
break;

case 2:
for ( int i = 1; i <= 12; i++ )

for( int j = 0; j <= 12; j++ ){

cout << "What is " << i << " + " << j << " = ";
sum = i + j;

if( answer == sum ) {
cout <<"Great Job!!!!!" << endl << endl;
correct++;
}
else {
cout << "Sorry " << i <<" + " << j << " = " << sum <<endl << endl;
wrong++;
}
}

cout << "You got " << correct <<" right and " << wrong << " wrong"<< endl<< endl;
cin.get();;
break;

case 3:
for ( int i = 12; i <= 22; i++ )

for( int j = 1; j <= 12; j++ ){

cout << "What is " << i << " - " << j << " = ";
sum = i - j;

if( answer == sum ) {

cout <<"Terrific!!!!!" << endl << endl;
correct++;
}
else {
cout << "Sorry " << i <<" - " << j << " = " << sum <<endl << endl;
wrong++;
}
}

cout << "You got " << correct <<" right and " << wrong << " wrong"<< endl<< endl;
cin.get();
break;

default:
break;

}

}while ( menu != 4 );
return 0;
}``````

Just replace the i and j loops to call rand().

For example, in the multiplication loop change:

``````case 1:
for ( int i = 1; i <= 12; i++ )

for( int j = 0; j <= 12; j++ ){

cout << "What is " << i << " X " << j << " = ";
product = i * j;

if( answer == product ) {
cout <<"Good Job!!!!!" << endl << endl;
correct++;
}
else {
cout << "Sorry " << i <<" X " << j << " = " << product<< endl << endl;
wrong++;
}
}``````

to

``````case 1:
i = rand()%50;
j = rand()%50;
cout << "What is " << i << " X " << j << " = ";
product = i * j;

if( answer == product ) {
cout <<"Good Job!!!!!" << endl << endl;
correct++;
}
else {
cout << "Sorry " << i <<" X " << j << " = " << product<< endl << endl;
wrong++;
}
cout << "You got " << correct <<" right and " << wrong << " wrong"<< endl<< endl;
cin.get();
break;``````

Don't forget to get rid of the extra set of {} when you make the conversions.
