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:
- The program starts by including the necessary header files,
stdio.h
andstring.h
, to handle input/output operations and string manipulation functions, respectively. - The
replaceMultipleBlanks
function is defined, taking a string as its parameter. - Inside the function, a loop is used to iterate through each character in the string.
- 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.
- If consecutive blanks are found, an inner loop is used to shift the subsequent characters to the left, effectively replacing the extra blanks.
- The
count
variable keeps track of the number of blanks removed, and thelength
variable is decremented accordingly. - Finally, the modified string is printed in the
main
function after calling thereplaceMultipleBlanks
function.

FAQs
It is essential to replace consecutive blanks with a single blank to improve the readability and aesthetics of the text. Multiple consecutive blanks can make the text appear cluttered and harder to understand. By reducing the number of blanks, the text becomes more visually appealing and easier to process.
Yes, the program can handle other whitespace characters, such as tabs or newlines, by modifying the condition in the replaceMultipleBlanks
function. Instead of checking for a blank (' '
), you can modify the condition to check for other whitespace characters.
No, the program we discussed is case-insensitive. It treats uppercase and lowercase characters as the same. If you want to make the program case-sensitive, you can modify it by considering the ASCII values of the characters.
To integrate this program into your own text-processing application, you can encapsulate the logic into a function or a module. By calling this function or module when needed, you can ensure that consecutive blanks are replaced by a single blank, improving the quality of your text processing.
The program we discussed performs the task of replacing consecutive blanks efficiently. However, it has a limitation when it comes to handling leading or trailing blanks. The current implementation does not remove leading or trailing blanks. If you want to handle those cases as well, you can extend the program accordingly.
Yes, you can use this program for languages other than English. The concept of replacing consecutive blanks with a single blank applies universally, regardless of the language. By incorporating this program into your text-processing applications, you can enhance the readability of text in various languages.
