Solution to scanf_s in vs

Workarounds for using scanf_s in Visual Studio include enabling security features, including header files, using the correct format specifier, and handling return values. Enabling security features requires that the runtime library be set to "Multi-Threaded (/MT)" and include the and header files. scanf_s uses different format specifiers, such as integer %d, float %f, character %c, and string %s. Check the return value to ensure the input was read successfully.

Problem:Using scanf_s in Visual Studio A problem was encountered with the function.

Solution:

1. Enable security features:

• Open the Visual Studio project properties page.
• Go to "Configuration Properties" > "C/C" > "Code Generation" > "Runtime Library".
• Set the "Runtime Library" option to "Multi-Threading (/MT)".

2. Include header files:

• Add the following header files in the code:

#include <stdio.h>
#include <stdlib.h>

3. Use the correct format specifier:

• The scanf_s function uses different format specifiers, different from scanf. Please use the following format specifiers:

Data Type	Format Specifier
Integer	%d
Floating point number	%f
Character	%c
String	%s

4. Processing return value:

• The scanf_s function returns an integer indicating the number of items successfully read. Check the return value to ensure the input was read successfully.
• For example:

int numScanned;
numScanned = scanf_s("%d", &number);
if (numScanned != 1) {
    printf("Error reading input.\n");
}

Example:

The following is an example of using the scanf_s function to read two integers:

int num1, num2;
scanf_s("%d %d", &num1, &num2);
