编程可以这么酷
在linux下，可以使用一些宏，加上自定义格式输出，让输出更易于调试：
排版出来可能有些乱，注意do{ }while(0);是在一行里就可以了。
#include <stdio.h>#include <stdlib.h>#define DEBUG1( fmt, arg ... ) \do{printf("[DEBUG] " fmt , ##arg ); }while(0);#define DEBUG2( fmt, arg ... ) \do{printf("[%s: %s: line %d]" fmt ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor1( fmt, arg ... )\do{printf("\033[30m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor2( fmt, arg ... )\do{printf("\033[31m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor3( fmt, arg ... )\do{printf("\033[32m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor4( fmt, arg ... )\do{printf("\033[33m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor5( fmt, arg ... )\do{printf("\033[34m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor6( fmt, arg ... )\do{printf("\033[35m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);#define PrintColor7( fmt, arg ... ) \do{printf("\033[36m""[%s: %s: line %d]" fmt"\033[0m" ,\__FILE__, __FUNCTION__, __LINE__, ##arg ); }while(0);int main(){printf("I AM IN macro.c\n");DEBUG1("I AM IN macro.c\n");DEBUG2("I AM IN macro.c\n");PrintColor1("I AM IN macro.c\n");PrintColor2("I AM IN macro.c\n");PrintColor3("I AM IN macro.c\n");PrintColor4("I AM IN macro.c\n");PrintColor5("I AM IN macro.c\n");PrintColor6("I AM IN macro.c\n");PrintColor7("I AM IN macro.c\n");return 0;}
输出结果：
