C语言的一些简单操作练习. 互换两个数字: # include <stdio.h> int main(void) { int i = 3; int j = 5; int t; //将i与j的值交换 t = i; i = j; j = t; printf("i = %d, j = %d\n", i, j); return 0; } 输出随意字符随意层的金字塔: # include<stdio.h> main() { int a,i,j; char c; pri…
大家能够敲写一下以下的练习代码.看下执行结果,都非常easy.关键要理解. if: # include <stdio.h> int main(void) { int i = 1; i = i + 1; if(i>10); i = 1; printf("%d\n", i); return 0; } if演示样例2: # include <stdio.h> int main(void) { int i; if (1 > 2) printf("哈…
