    inserting a space

    How would I go about inserting a space into an array I have gotten, say from a file. ex
    Code:
    fgets(array,sizeof array,file);
    Now where would I go. I don't want to create a new array or use malloc. Is there a way with say pointers or something? TIA

    Does the existing array contain enough room?

    Since you are using fgets I'm assuming an array of characters and specifically a null terminated array

    To say insert a space after the 4th element
    Code:
    for ( c = strlen(array) /* Want to move null character also */; c > 3; c--)
    {
      array[c+1] = array[c];
    } 
    
    array[c+1]=' ';
    This will only work if you have enough room in the array already.
