C code to remove spaces or excess blanks from a string, For example consider the string
"c programming". It will remove spaces when they occur more than one time consecutively in string anywhere.
"c programming"There are two spaces in this string, so our program will print a string
"c programming". It will remove spaces when they occur more than one time consecutively in string anywhere.
C programming code
#include <stdio.h> int main() { char text[100], blank[100]; int c = 0, d = 0; printf("Enter some text\n"); gets(text); while (text[c] != '\0') { if (!(text[c] == ' ' && text[c+1] == ' ')) { blank[d] = text[c]; d++; } c++; } blank[d] = '\0'; printf("Text after removing blanks\n%s\n", blank); return 0; }
C programming code using pointers
#include<stdio.h> #include<string.h> #include<stdlib.h> #define SPACE ' ' main() { char string[100], *blank, *start; int length, c = 0, d = 0; printf("Enter a string\n"); gets(string); length = strlen(string); blank = string; start = (char*)malloc(length+1); if ( start == NULL ) exit(EXIT_FAILURE); while(*(blank+c)) { if ( *(blank+c) == SPACE && *(blank+c+1) == SPACE ) {} else { *(start+d) = *(blank+c); d++; } c++; } *(start+d)='\0'; printf("%s\n", start); free(start); return 0; }
