passing arrays
I'm having some trouble figuring out how to pass arrays. I need to write a function with 3 parameters: a,b,i. A and B are char arrays. The parameter i is an int. The function inserts the string a into b immediately after index i. Assume b is large enough to hold the added characters.
So an example of what I'm trying to do is the following...
A is "Today Wednesday"
b is "is"
i is 6
and the result of the function would be
Today is Wednesday
I believe you can use pointers to pass the arrays if you donot know how to do so i can look up an example of such a code for you
Code:// this is the prototype void insert_word( char line[], char word[], int pos ); // example use int main ( ) { char buff[100] = "Today Wednesday"; char insert[] = "is"; insert_word( buff, insert, 6 ); return 0; }
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
you want something exact ne??? so it will be
Code:memmove(a+i+strlen(b)-1, a+i,strlen(a)-i) /*i'm not sure about this, i mean, i dont know if the arguments are in the correct order for this function, i used memmove(dest,source, num)*/ memcpy(a+i,b,strlen(b)-1) /*again used memcpy(dest,source, num) but i'm not sure about the order of the arguments*/
