strcpy() is a standard library function in C/C++ and is used to copy one string to another. In C it is present in string.h header file and in C++ it is present in cstring header file.
char* strcpy(char* dest, const char* src);
Paramters: This method accepts following paramters:
- dest: Pointer to the destination array where the content is to be copied.
- src: string which will be copied.
Return Value: After copying the source string to the destination string, the strcpy() function returns a pointer to the destination string.
Below program explains different usages of this library function:
str1: Hello Geeks! str2: Hello Geeks! str3: copy successful str4: GfG
- This function copies the entire string to the destination string. It doesn’t append the source string to the destination string. In other words, we can say that it replaces the content of destination string by the content of source string.
- It does not affect the source string. The source string remains same after copying.
- This function only works with C style strings and not C++ style strings i.e. it only works with strings of type char str; and not string s1; which are created using standard string data type available in C++ and not C.
