  • 字符串和字符串函数

    函数:

     gets(),puts(),strcat()

    strncat(),strcmp(),strncmp()

    strcpy(),strncpy()

    sprintf(),strchr()

    先看gets()和puts()函数吧。

    int main(void)
    {
    	char name[LINELEN];
    	char talents[LINELEN];
    	int i;
    	const char m1[40] = "Limit yourself to one line's worth.";
    	const char m2[] = "If you can't think of anything,fake it";
    	const char *m3 = "\nEnough about me - what's your name?";
    	const char *mytal[LIM] = 
    	{
    		"Adding numbers swiftly",
    		"Multiplying accurately",
    		"Following instructions to the letter",
    		"Understanding the C languge"
    	};
    
    	printf("Hi I'm Clyde the Computer,"" I have many talents.\n");
    
    	printf("Let me tell you some of them.\n");
    
    	puts("What were they?Ah,yes, here's a partial list.");
    	for(i = 0; i < LIM; i++)
    		{
    			puts(mytal[i]);
    		}
    	puts(m3);
    	gets(name);
    	printf("Well, %s, %s\n",name,MSG);
    	printf("%s\n%s\n",m1, m2);
    	gets(talents);
    	puts("Let's see if I've got that list: ");
    	puts(talents);
    	printf("Thanks for the information,%s, \n",name);
    	return 0;
    	
    }
    

     下面再看看还有一些情况要注意的:

    char greeting[50] = "Hello, and" "how are" "you" "today!";
    这句就是ANSI C会将其串联起来
    

     还有就是想要输出“的话那么就使用\这个符号

    再看一个把字符串看做指针

    #include<stdio.h>
    
    int main(void)
    {
            /*%s格式将输出字符串We,%p格式产生一个地址。*/ 
    	printf("%s, %p, %c\n", "We","are", *"space farers");
         /*这里主要是*后面的那些字符串当做指针,那个就是指向字符串的第一字母,也就是代表第一个字母的地址然后就是取内容了*/
    	return 0;
    }
