Following is the C program to swap two strings by using strcpy() function − Live Demo #include<stdio.h> #include<string.h> main(){ char s1[10],s2[10],s3[10]; printf("Enter String 1"); gets(s1); printf("Enter String 2"); gets(s2); printf("Before Swapping"); printf("Strin...
Returns the destination string. No return value is reserved to indicate an error. Examples: strcpy() function Example 1: How strcpy() copies the contents of string2 to string1 This example demonstrates how strcpy() copies the contents of string2 to string1. Initially, both string1 and string...

下面是一个修改后的版本，带有一个通用的swap函数，并定义了行为：不能使用同一个函数来交换指针和数组。
