How can you read a string input including spaces using 'scanf()' in C?

To read a string input that includes spaces using scanf() in C, you can use the fgets() function instead. The scanf() function with the %s format specifier stops reading at the first whitespace, which means it won't capture spaces. Here's how you can use fgets():

#include <stdio.h>

int main() {
    char str[100];

    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);

    printf("You entered: %s", str);

    return 0;
}

Explanation:

• fgets(str, sizeof(str), stdin); reads a line of text from standard input, including spaces, until a newline character is encountered or the specified limit is reached.
• This method is safer than scanf() for reading strings, as it prevents buffer overflow by limiting the number of characters read.
