C language function call example子
#include <stdio.h>
#define LABEL '*'
#define NAME "王五"
#define AGE 35
void printSplit(void);
int main()
{
printSplit();
printf("姓名：%s\n", NAME);
printf("年龄：%d\n", AGE);
printSplit();
return 0;
}
void printSplit(void) {
for (size_t i = 0; i < 10; i++)
{
putchar('*');
}
putchar('\n');
}Note: The printSplit function is in the main function behind, so it needs to be declared in front.
Result:
********** 姓名：王五 年龄：35 **********
