Question

2. You are to write a subroutine/function which will expect a string as input. The function should locate any instances of multiple space characters together. The function should modify the string to replace all mulktiple-space blocks with single spaces. No non-space characters should be altered Example: The string "Bob has twelve has twelve apples." apples." should be altered to become "Bob

C language please

Answer 1

#include<stdio.h>
#include<string.h>
void removeSpace(char str[])
{
int flag=0,i,j=0,len = strlen(str);
char improvedString[len];
for(i=0;i<len;i++)
{
if(flag==0&&str[i]!=' ') //checks whether the next character is not a space
{
improvedString[j]=str[i];
j++;
}
else if(flag==0&&str[i]==' ') //checks if it is the first space
{
improvedString[j]=str[i];
j++;
flag=1;
}
else if(flag==1&&str[i]!=' ') //checks if the next character is space or not and resets flag
{
improvedString[j]=str[i];
j++;
flag=0;
}
}
improvedString[j]= '\0';
puts(improvedString);
}
int main()
{
char str[1000];
printf("Enter any string :");
gets(str);
removeSpace(str);
}
