Outputting function result to an array

Shufty · #1 07-May-2004, 10:19

Hi, I'm trying to generate a random number and output the result to the first part of an array, then a new random number to the second part etc.
Here's the code for the random number I'm using (the appropriate headers are being used too)

int random_number;
srand((unsigned int)time((time_t *)NULL));
random_number = (rand()%49)+1;

I want to output the result of this into an array called winning[n]

Any help anyone can give would be greatly appreciated!

1st i duno how much size u need for ur winning[n] array,
so i simply assign n=49;

CPP / C++ / C Code:

int main()
{
int random_number;
srand((unsigned int)time((time_t *)NULL));
//random_number = (rand()%49)+1;

const int n = 49;// i don't know wht size u need for u winning[n]
// so i simply put 49
int winning[n];

for ( int i =0; i<n; i++ )
{
winning[i]=(rand()%49)+1;// generate random num for ur winning[n]
cout<<winning[i]<<endl;
}

thanks! I'll let you know if I can get it to work with the rest of my code (I'm not very good at this stuff)

Let's simplify:

CPP / C++ / C Code:

srand(time(NULL));  // call ONLY ONCE in the program
winning[n] = (rand()%49)+1;
