Question

void empty_spaces(char array[]){
 int j=0,i=0,n=0;
 n=strlen(array);
 while(i<n){
    if(array[i]==' '){
        j=i;
        while(j<n){
             array[j]=array[j+1];
             ++j;
        }
        --n;
    }else
         ++i;
 }
 if(n>15)
         n=15;
 array[n]='\0';
}

Could someone explain me, this code? This function cleans up the empty spaces in array, but could someone explain me exactly what it works?

Answer 1

It loops over every character in the array, removing all ‘ ‘ (space) characters. The inner loop is what does the erasing. When the outer loop finds a space character, the inner loop “shifts” the rest of the array to the left one index, overwriting the space.
