编写代码如下:
#include <stdio.h> #include <string.h> #include <stdlib.h> #include <time.h> int main(int argc, char **argv) { int a[30],b[30]; int i,c,d; srand((unsigned int)time(NULL)); for (i = 0; i < 30; i++) { a[i] = rand()%101; b[i] = rand()%101; printf("%d......%d+%d=\n", i+1,a[i],b[i]); } printf("按任意键查看答案"); getchar(); for (i = 0; i < 30; i++) { printf("%d......%d+%d=%d\n", i+1,a[i],b[i],a[i]+b[i]); } getchar(); return 0; }
运行结果如下:
