Explanation:

• #include <stdio.h>: Includes the standard input-output header file for input/output operations.
• #include <string.h>: Includes the string manipulation functions header file.
• void cleanNameSpaces(char *str): Function declaration for cleanNameSpaces that takes a string pointer str as input and removes extra spaces from it.
• int i, j;: Declaration of variables for looping through the string.
• int length = strlen(str);: Calculates the length of the input string using strlen function from <string.h>.
• int inside_space = 0;: Flag to track whether the loop is inside consecutive spaces or not.
• for (i = 0, j = 0; i < length; i++) { ... }: Loop to iterate through each character of the string.
• if (str[i] != ' ') { ... }: If the character is not a space, it is copied to the new string str[j++].
• else { ... }: If the character is a space, it checks whether it's already inside a consecutive space or not.
• str[j] = '\0';: Adds the null terminator at the end of the modified string to signify the end of the string.
• int main() { ... }: Entry point of the program.
• char str[100];: Declares a character array to store the input string.
• printf("Enter a string with extra spaces: ");: Asks the user to input a string with extra spaces.
• fgets(str, sizeof(str), stdin);: Reads the input string from the user, including spaces, and stores it in str.
• str[strcspn(str, "\n")] = '\0';: Removes the newline character from the string input by replacing it with the null terminator.
• cleanNameSpaces(str);: Calls the cleanNameSpaces function to remove extra spaces from the input string.
• printf("String after removing extra spaces: %s\n", str);: Prints the modified string after removing extra spaces.
