Here’s an example of such a program:

#include <stdio.h>
#include <string.h>

void replaceMultipleBlanks(char* str) {
    int i, j;
    int length = strlen(str);
    int count = 0;

    for (i = 0; i < length; i++) {
        if (str[i] == ' ' && str[i + 1] == ' ') {
            for (j = i + 1; j < length - count; j++) {
                str[j] = str[j + 1];
            }
            count++;
            length--;
            i--;
        }
    }
}

int main() {
    char text[] = "This   is   an   example    text.";
    
    printf("Original text: %s\n", text);
    replaceMultipleBlanks(text);
    printf("Modified text: %s\n", text);
    
    return 0;
}

In this program, we define a function called replaceMultipleBlanks that takes a string as an argument.

The function iterates through the string and checks for consecutive blanks. If two or more consecutive blanks are found, the function shifts the subsequent characters to the left to replace the extra blanks.

Finally, the modified string is printed.

How Does the C Program Work?

The C program we discussed works by iterating through the input string and identifying consecutive blanks.

Once consecutive blanks are detected, the program removes the extra blanks by shifting the subsequent characters to the left.

Let’s break down the steps involved:

1. The program starts by including the necessary header files, stdio.h and string.h, to handle input/output operations and string manipulation functions, respectively.
2. The replaceMultipleBlanks function is defined, taking a string as its parameter.
3. Inside the function, a loop is used to iterate through each character in the string.
4. The loop checks if the current character is a blank and if the next character is also a blank. If this condition is true, it means that there are consecutive blanks.
5. If consecutive blanks are found, an inner loop is used to shift the subsequent characters to the left, effectively replacing the extra blanks.
6. The count variable keeps track of the number of blanks removed, and the length variable is decremented accordingly.
7. Finally, the modified string is printed in the main function after calling the replaceMultipleBlanks function.
