Using a variable as a partial value for another variable?

Question

Is there a simple way to set the value of a variable to the concatenated values of other variables of mixed types?

For example, something that accomplishes the same thing as this...

int card=10;
char card_suit='c';
char card_picture[255];
FILE *x


x=fopen("streamy.txt", "w");
fprintf(x, "%d%c.bmp\n", card, card_suit);
fclose(x);

x=fopen("streamy.txt", "rt");
fscanf(x, "%s", &card_picture);
fclose(x);

But not dumb.

Am I missing something super obvious?

I believe you're looking for snprintf() and its relatives:

char card_picture[255];

snprintf(card_picture, sizeof(card_picture), "%d%c.bmp", card, card_suit);
