Answer: True

Step by step solution

Understanding strcpy function

The strcpy function is a standard library function in C and C++ programming languages, used to copy one string to another. It takes two string arguments: the destination string and the source string. The syntax for the strcpy function is: `strcpy(destination, source);`. The function copies the source string, including the null terminator, to the destination string.

Analyzing the behavior of strcpy

When the strcpy function is called with two string arguments (destination and source), it will overwrite the contents of the destination string with the contents of the source string. It starts copying from the first character of the source string to the first character of the destination string and continues until the null terminator of the source string is copied. As a result, the original contents of the destination string will be overwritten and replaced with the source string.

Evaluating the given statement

Based on our understanding of the strcpy function, it does overwrite the contents of its first string argument (destination string). It copies the characters of the source string, including the null terminator, to the destination string.

Conclusion

The given statement is True. The strcpy function will overwrite the contents of its first string argument (destination string) when copying the source string to the destination string.
