C语言完美演绎7-15

/* 范例：7-15 */

#include <string.h>

#include <stdio.h>

void main(void)

{

/* 定义参数dest的字符数组destination25 */

char destination25;

/* 定义参数scr的字符指针scr1、scr2、scr3 */

char *scr1 = "tiger" , *scr2 =" is", *scr3 = " braveaaaaa" ;

char *a,*b;

strcpy(destination, scr1);

printf("%s\n", destination);

/* 将参数scr2中的字符串加到参数destination的字符串之后 */

a = strcat(destination, scr2);

printf("%s\n", destination);

printf("a=%s (void*)a=%u\n", a,sizeof(destination));

/* 将参数scr3的字符串前6个字符加到参数destination的字符串之后 */

b = strncat(destination, scr3,6);

printf("%s\n", b);

getchar();}

}

程序执行结果：

tiger

tiger is

a=tiger is (void*)a=25

tiger is brave
