reduce space char function question..

there is no mistake..

they say that if the "if" statement is true then do this

Code:

---

strcopy(str+i,(str+i+1))

---

what this line does??

if you look again on the if statement you'll see that this line will work if the current character is 'i'

the strcopy above removes this character from the string... So where do you see processing of spaces here?

the if statement is
if (!i||str[i-1]==' '||i==strlen(str)-1)
this if does make any sense
??

this if makes sence, the outer loop seems to be wrong

Code:

---

void *(char *str)
{
    int i;
    for(i=0;str[i];i++)
        if(str[i]=='i')
                if ((!i)||str[i-1]==' '||(i==strlen(str)-1)
                {
                    strcpy(str+i,(str+i+1));
                    i--;
                }
}

---

is this function ok??

do you have a compiler?

i mean logickly

if you fix compilation errors this function will removes spaces that follow character 'i'.

Is it logical?

yes but i dont have a compiler in my exam

so can you tell me if its ok?

no, I cannot tell you if it is ok that your code could not be compiled
and I cannot tell you if it is ok to remove spaces after character 'i' instead of spaces after spaces.

You need to decide it yourself

how to do it
if you dont have a compiler
?

Do your best and double check your work. Even if you are very good, you can make a mistake, but that's okay, since the other people taking the exam will be facing the same problem.

i cant understand some of the if statement
why ''i" could to be null

why we copy one string into another when
the first string is smaller by size
it cannot be
??
