C program to remove white spaces from a string; Through this tutorial, we will learn how to remove white spaces from a string using for loop, recursion and while loop in c programs.
Programs to Remove White Spaces from a String in C
- C Program to Remove White Spaces from a String using For Loop
- C Program to Remove White Spaces from a String using While Loop
- C Program to Remove White Spaces from a String using Recursion
C Program to Remove White Spaces from a String using For Loop
#include <stdio.h>
int main()
{
char str[100];
int i, j = 0;
printf("Enter String to Remove White Spaces = ");
gets(str);
printf("String before Removing Empty Spaces = %s\n", str);
for(i = 0; str[i] != '#include <stdio.h>
int main()
{
char str[100];
int i, j = 0;
printf("Enter String to Remove White Spaces = ");
gets(str);
printf("String before Removing Empty Spaces = %s\n", str);
for(i = 0; str[i] != '\0'; i++)
{
str[i] = str[i + j];
if(str[i] == ' ' || str[i] == '\t')
{
j++;
i--;
}
}
printf("String after Removing Empty Spaces = %s\n", str);
}'; i++)
{
str[i] = str[i + j];
if(str[i] == ' ' || str[i] == '\t')
{
j++;
i--;
}
}
printf("String after Removing Empty Spaces = %s\n", str);
}
The output of the above c program; as follows:
Enter String to Remove White Spaces = hello world String before Removing Empty Spaces = hello world String after Removing Empty Spaces = helloworld
C Program to Remove White Spaces from a String using While Loop
#include <stdio.h>
int main()
{
char str[100];
int i, j, k;
printf("Enter String to Remove White Spaces = ");
gets(str);
printf("String before Removing Empty Spaces = %s\n", str);
i = 0;
while(str[i] != '#include <stdio.h>
int main()
{
char str[100];
int i, j, k;
printf("Enter String to Remove White Spaces = ");
gets(str);
printf("String before Removing Empty Spaces = %s\n", str);
i = 0;
while(str[i] != '\0')
{
k = 0;
if(str[i] == ' ' || str[i] == '\t')
{
j = i;
while(str[j - 1] != '\0')
{
str[j] = str[j + 1];
j++;
}
k = 1;
}
if(k == 0)
{
i++;
}
}
printf("String after Removing Empty Spaces = %s\n", str);
}')
{
k = 0;
if(str[i] == ' ' || str[i] == '\t')
{
j = i;
while(str[j - 1] != '#include <stdio.h>
int main()
{
char str[100];
int i, j, k;
printf("Enter String to Remove White Spaces = ");
gets(str);
printf("String before Removing Empty Spaces = %s\n", str);
i = 0;
while(str[i] != '\0')
{
k = 0;
if(str[i] == ' ' || str[i] == '\t')
{
j = i;
while(str[j - 1] != '\0')
{
str[j] = str[j + 1];
j++;
}
k = 1;
}
if(k == 0)
{
i++;
}
}
printf("String after Removing Empty Spaces = %s\n", str);
}')
{
str[j] = str[j + 1];
j++;
}
k = 1;
}
if(k == 0)
{
i++;
}
}
printf("String after Removing Empty Spaces = %s\n", str);
}
The output of the above c program; as follows:
Enter String to Remove White Spaces = c program String before Removing Empty Spaces = c program String after Removing Empty Spaces = cprogram
C Program to Remove White Spaces from a String using Recursion
#include <stdio.h>
#include <string.h>
void deleteblankspaces(char *s)
{
static int i,k=0;
if(s[i])
{
s[i]=s[i+k];
if(s[i]==' '|| s[i]=='\t')
{
k++;
i--;
}
i++;
deleteblankspaces(s);
}
}
int main()
{
char s[1000];
printf("Enter the string : ");
gets(s);
deleteblankspaces(s);
printf("string after removing all duplicates:");
printf("%s",s);
return 0;
}
The output of the above c program; as follows:
Enter the string : hello world string after removing all duplicates:helloworld
