Pull request overview

Adds a new C source file under the unit test tree that implements an interactive string-reversal program.

Changes:

• Introduces source/test/testing_purpose.c with a reverseString() helper and an interactive main() that reads from stdin and prints results.

This file adds an interactive standalone main() program under source/test, but it is not referenced by source/test/Makefile.am (the unit test build enumerates sources explicitly). If this is intended as a unit test, convert it into a gtest test and add it to PsmSsp_gtest_bin_SOURCES; otherwise consider removing it or relocating it outside the test tree to avoid dead/accidental test artifacts in the repo.

Suggested change

	int main() {
	char str[100];
	printf("Enter a string: ");
	fgets(str, sizeof(str), stdin);
	// Remove newline if present
	str[strcspn(str, "\n")] = 0;
	reverseString(str);
	printf("Reversed string: %s\n", str);
	return 0;
	}

reverseString performs I/O (printf) in addition to reversing the buffer, and main() prints the reversed string again. Consider keeping reverseString focused on mutation only and letting the caller decide whether/how to print, to avoid duplicated output and make the function reusable in unit tests.

Suggested change

printf("string reversed : %s\n",str);

[Copilot]

fgets return value is not checked. If stdin is closed or an error occurs, str contents are undefined and strcspn/reverseString will operate on uninitialized data. Handle a NULL return from fgets (e.g., print an error and return non-zero) before using str.

Suggested change

	fgets(str, sizeof(str), stdin);
	if (fgets(str, sizeof(str), stdin) == NULL) {
	fprintf(stderr, "Error reading input.\n");
	return 1;
	}

reverseString has external linkage but appears intended for use only within this file. Mark it static to avoid exporting an unnecessary symbol from the test binary (and potential link conflicts if another test adds the same helper name).

Suggested change

	void reverseString(char *str) {
	static void reverseString(char *str) {
