i am trying to enter 3 string into an array . And then print out the reverse of the strings.
my code below is not working.
Any help would be greatly appreciated
Code:#include<stdio.h> int main () { char *words[24]; /*declare an array of pointers*/ int i; printf ("Enter 3 words into an array"); for(i =0; i<=3; ++i) scanf ("%s", ¬es[i]); for(i =3; i>=0; --i) printf ("%s", notes[i]); return 0; }
>for(i =0; i<=3; ++i)
That's not 3 strings, that's 4 strings. Make it:
> char *words[24]; /*declare an array of pointers*/Code:for(i =0; i<3; ++i)
This doesn't declare any memory for the actual string, it just declares 24 pointers. Either make this an array of strings:
Or allocate space for each string:Code:char words[24][40]; /*declare an array of 24 strings*/
And your declaration is called words, but your loop refers to notes.Code:#include <stdio.h> #include <string.h> . . char *words[24]; /*declare an array of pointers*/ char temp[100]; . . for(i =0; i<3; ++i) { scanf("%s", &temp); notes[i] = malloc(strlen(temp)+1); strcpy(notes[i], temp); }
You have a variable called words, but no variable called notes.
words is just an array of pointers, which don't point anywhere.
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.
thank you. Have got both suggestions to work. Notes was a typo. Apologies
