how to use gets after scanf

To use gets after scanf in C, you can follow these steps:

1. Declare a character array to store the input using scanf.
2. Use scanf to read the input from the user and store it in the character array.
3. Use gets to read any remaining characters from the input buffer.

Here's an example code snippet:

#include <stdio.h>

int main() {
    char input[100];
    int number;

    printf("Enter a number: ");
    scanf("%d", &number);

    // Clear the input buffer
    while (getchar() != '\n');

    printf("Enter a string: ");
    gets(input);

    printf("Number: %d\n", number);
    printf("String: %s\n", input);

    return 0;
}

In this example, scanf is used to read an integer from the user and store it in the number variable. After that, gets is used to read a string from the user and store it in the input array.

Please note that using gets is generally discouraged due to potential buffer overflow vulnerabilities. It is recommended to use safer alternatives like fgets instead.
