C examples for Data Type:Random Number
The following program contains an example of if.
It generates the magic number using the standard random number generator rand( ), which returns an arbitrary number between 0 and RAND_MAX.
RAND_MAX defines an integer value that is 32,767 or larger.
The rand( ) function requires the header <stdlib.h> .
#include <stdio.h> #include <stdlib.h> int main(void) { int magic; /* magic number */ int guess; /* user's guess */ magic = rand(); /* generate the magic number */ printf("Guess the magic number: "); scanf("%d", &guess); if (guess == magic) printf("** Right **"); return 0;//from w ww . j a v a2 s . c o m }
