最近有点忙,不是英语就是C语言,我准备考研了#include <stdio.h>int main(){ int number; scanf("I say %d",&number); printf("Computer says %d",number);return 0;}#include <stdio.h>int main(){ int first; int second; scanf("%d+%d", &first,&second); printf("=%d",first+second);return 0;}#include <stdio.h>int main() { int A; int B; int C; scanf("%d+%d+%d",&A,&B,&C); printf("%d",A+B+C); return 0;}C语言在于只要错一个字符,就运行不了,就很痛苦,多一个少一个次序错一个都不行!
