C语言main()函数的参数问题详解
#include<stdio.h>
void main(int argc, char* argv[])
{
while (argc > 1)
{
++argv;
printf("%s\n", argv);
--argc;
}
}
#include<stdio.h>
#include<stdlib.h>
void main(int argc, char* argv[])
{
int i;
printf("The number of string is: %d\n", argc - 1);
for (i = 1; i < argc; i++)
{
printf("the string %d is:%s\n", i, argv[i]);
}
}
#include<stdio.h>
void main(void)
{
const char* str = "Welcome to Fishc.com!\n\n";
//这个语句的含义是：声明一个名为str的指针变量，
//它指向一个字符型变量，初始化str为指向字符串
//"Welcome to Fishc.com!\n\n"
#if(0)
str[0] = 'w';
#endif
str = "I love Fisfc.com!\n\n";
printf("\n\n%s", str);
}
#include<stdio.h>
void main(void)
{
char* const str = "Welcome to Fishc.com!\n\n";
//常量指针是一个固定的指针，不可以改变它的值，但它所指的数据可以改变
str[0] = 'w';
#if(0)
str = "I love Fisfc.com!\n\n";
#endif
printf("\n\n%s", str);
}
