Hey guys i m New to C and i was just learning pointer to structure i need help thanks
Code:#include <stdio.h> struct cd { int x; int lol; }; read(int *e) { printf("Please enter number: "); scanf("%d",&e->x); printf("Number is %d",*e->x); } int main(void) { int x; read(&x); return 0; }
I suppose read should take a pointer to struct cd, not a pointer to int.
Just because struct cd has a member named x doesn't mean that if you have an int x in main it will be the same thing. Here is your code with a couple of changes so that it will compile, and in a more readable format:
I added the line in green, and the \n's...it's just like christmas!Code:#include <stdio.h> struct cd { int x; int lol; }; read(int *e) { printf("Please enter number: "); scanf("%d",e); printf("Number is %d\n",*e); } int main(void) { struct cd mkcd; read(&mkcd.x); printf("Number is %d\n",mkcd.x); return 0; }
C programming resources:
GNU C Function and Macro Index -- glibc reference manual
The C Book -- nice online learner guide
Current ISO draft standard
CCAN -- new CPAN like open source library repository
3 (different) GNU debugger tutorials: #1 -- #2 -- #3
cpwiki -- our wiki on sourceforge
thanks alot mate and happy christmas
