What does strcpy stand for in C language?

The strcpy function is used in C language to copy a source string to a destination string. Function prototype: char strcpy(char dest, const char *src); Parameters: destination string address dest, source string address src (which is a constant). Return value: Returns the address of the target string dest. How it works: The strcpy function copies the contents of the source string src to the destination string dest character by character until it encounters the null character ('\0') of the source string. The null character represents the end of the string and will also be copied to the destination string.

The meaning of strcpy in C language

strcpy The function is in the C standard library A string manipulation function used to copy a source string into a target string.

Function prototype:

<code class="c">char *strcpy(char *dest, const char *src);</code>

Parameters:

• dest: Destination string address.
• src: Source string address (as a constant).

Return value:

Return the address of the target string dest.

Working principle:

strcpy The function copies the contents of the source string src character by character to the target character string dest until the null character ('\0') of the source string is encountered. The null character represents the end of the string and will also be copied to the target string.

Example:

<code class="c">char source[] = "Hello";
char destination[10];

strcpy(destination, source);

printf("Destination string: %s\n", destination);</code>

Output:

<code>Destination string: Hello</code>

Note:

strcpy The function does not check the size of the destination string dest, so a buffer overflow may occur if the destination string is too small. To avoid this problem, use the strncpy function, which truncates the string when copying the specified number of characters.
