Chapter 10: Problem 40

T \(F\) The strcpy function will overwrite the contents of its first string argument.

Short Answer

Expert verified
Explain the behavior of the strcpy function. Answer: The statement is true. The strcpy function in C programming language overwrites the contents of its first string argument (destination string) with the contents of its second string argument (source string), including the null-character, during the copy process.

Step by step solution

01

Understand the strcpy function

The strcpy function is a part of the C programming language's standard library, and it copies the contents of one string (source) into another string (destination). The prototype of strcpy function is: `char *strcpy(char *destination, const char *source);` where the destination is the first string argument, and the source is the second string argument.
02

Analyze the overwriting behavior

When the strcpy function is called, it starts copying the characters from the source string (including the null-character, '\\0') into the destination string. During this process, any pre-existing contents of the destination string are overwritten by the characters from the source string until the null-character is found in the source string.
03

Evaluate the given statement

The statement is "The strcpy function will overwrite the contents of its first string argument." Based on our analysis, this statement is True because the strcpy function does overwrite the contents of the destination string (the first string argument) with the contents of the source string during the copy process.
