One of the problems encountered after the installation of the programing language C in Microsoft Visual Studio sometimes the number lines are not displayed automatically which you have to do it manually.
To solve this we are going to write a program:
Where we are going to write a program where we are going to ask someone’s age by asking his birth year.
After you run your code you have a message saying :
“Return value ignored: ‘scanf’ “
“ ‘scanf’ : this function or variable may be unsafe ”
To solve this you have to add this code #pragma warning(disable:4996)
The green line in the scanf code will still but your code will run without any problem.
The output after running the code this time
#pragma warning(disable:4996)
To turn off the warning within a file for everything that follows, use the warning pragma.
If you want you can copy the code from here :
int age;
int birth_year;
printf(” Enter your birthyear “);
scanf(“%d”, &birth_year);
age = 2022 – birth_year;
printf(” your age is = %d\n “, age);
