Thread: arrays of random integers & time

i am new i have two questions about functions

1.I need to know how to test my program with a loop of 25 repetitions

2. generate an attack location with rand() function. and pass the variable row and col by refernces

What have you tried so far?

i dont have anything in the main(),i am so stumped i jus need a kick in the right direction

Well a loop would be
for ( int i = 0 ; i < 25 ; i++ )

Picking random numbers is in the FAQ
http://faq.cprogramming.com/cgi-bin/...&id=1043284385

Passing by reference,

Code:

void foo ( int &a ) {
}
int main ( ) {
    int bar;
    foo( bar );
}

thank u,but this doesnt help me pass it thru columns and rows

THANk U,and how long did it take u to understand this

this is what i got i am still confused:

int main ()
{
srand(time(NULL));
int a = rand();
int row,col;
funcrand(row,col);
for (int i= 0 ; i< 25 ; i++ )
row= rand();
return 0;

Code:

#include <iostream>
void foo ( int &a ) {
    a = 2
}
int main ( ) {
    int bar = 1;
    std::cout << bar;
    foo( bar );
    std::cout << bar << std::endl;
}

doesnt it have to be random and its output is suppose to be in rows and columns and run 25 times

Unless you only want to loop through one line, you need to put curly braces ( { } 's ) around the code you want to execute 25 times. You'd also have a problem if you had a semicolon after the for statement.

this what i got
int main ( )
{
srand( (unsigned)time( NULL) );
for (int times=0;times<25;times++)
int a;
int b;
int grid[25][25];
int random_integer;
for (int a = 0; a<25; a++){
for (int b = 1; b<25; b++){
{random_integer=rand();
cout<<1 + rand() % 10 << a << 1+ rand() % 10 << b <<endl;}
funcrand(a,b);
return 0;
}

but when i run it says unexpected end of file as its error,wut is the problem
