首先你要理解什么是格式符，C语言中常用的格式符有哪些?
例：%s字符串 %d十进制数字 %\p地址 %f浮点数
在printf里格式化输出是要一个变量替换的作用，举例如下
int main(){ int num = 20; float flo = 13.5; char str[30] = "my name is frind"; printf("%d,%f,%s",num,flo,str); } 输出为:20 13.5 my name is frind -

不一定啊，比如：
#include<stdio.h> { void main() { printf("Hello World!!"); } }这里就没有用格式符。
