Error is:
Error C4996 'ctime': This function or variable may be unsafe. Consider using ctime_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

What I have tried:

#include<iostream>
#include<ctime>
using namespace std;
int main()
{
	time_t now = time(0);
	//Convert time to string form
	char *tm = ctime(&now);
	cout << "Time of System is: " << tm << endl;
	system("pause");
	return 0;
}<pre>

Solution 1

It's not an error, it's a warning. You are using an outdated function (it's been Depreciated[^] ) and it's suggesting a more modern version: ctime, ctime_s - cppreference.com[^]
You can ignore it for a simple program like this, or use the newer code.

See ctime_s, _ctime32_s, _ctime64_s, _wctime_s, _wctime32_s, _wctime64_s[^].
