this is a program in which u will hav 2 enter any 5 nos between 1 to 49 and if the number matches with the numbers chosen by the computer, u will win the lottery




#include <cstdlib>

void lotto();
void calc(int * a, int * b);
void menu();
// Main function. Seeds random function
// and calls menu function.
int main()


{

menu();
}
// This function prompts the user to pic
// k five numbers between 1 and 49.
// The function makes sure that the user
// picks numbers between 1 and 49,
// and that the user does not choose dup
// licate numbers. Then the computer
// chooses five random numbers. Error co
// ntrol is used to check if the
// computer chooses the same number twic
// e. Then the numbers are displayed
// to the screen. Finally the calc funct
// ion is called to calculate and
// output the results of the game...
