C code to remove spaces or excess blanks from a string, For example consider the string
“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 textn");
gets(text);
while (text[c] != '')
{
if (!(text[c] == ' ' && text[c+1] == ' ')) {
blank[d] = text[c];
d++;
}
c++;
}
blank[d] = '';
printf("Text after removing blanksn%sn", 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 stringn");
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)='';
printf("%sn", start);
free(start);
return 0;
}
