Thread: re:array of notation (full code)

hi, i trying to list out the array of power,amps,res
and vots input by user.
But only available to list out the first input of power,amps..etc.
Second input gave me 0s.

thanks in advance...

#include <conio.h>
#include <stdlib.h>
#include <ctype.h>
#define SIZE 50



char input[SIZE];
int choice;
float vots[SIZE],amps[SIZE],res[SIZE],power[SIZE],*v,*i,*r,*p;

*v=vots;
*i=amps;
*r=res;
*p=power;

void main()
{
some codes...
