Concat LPSTR in C++
- by Cat Man Do
Trying to use as basic C++ as I can to build a list of numbers from 1-52 in a random order (deck of cards). Unfortauntely, all my attempts to concat the strings and get a result end in failure. Any suggestions? NOTE: This is not homework it's something I'm using to create a game.
// Locals
char result[200] = ""; // Result
int card[52]; // Array of cards
srand(time(0)); // Initialize seed "randomly"
// Build
for (int i=0; i<52; i++) {
card[i] = i; // fill the array in order
}
// Shuffle cards
for (int i=0; i<(52-1); i++) {
int r = i + (rand() % (52-i));
int temp = card[i]; card[i] = card[r]; card[r] = temp;
}
// Build result
for (int c=0; c<52; c++) {
// Build
sprintf(result, "%d", card[c]);
// Comma?
if ( c < 51 )
{
sprintf(result, "%s", ",");
}
}
My end result is always garbled text. Thanks for the help.
