This thing is giving me error. C Language -

how can fix this? want scanf() value d, how can it? need please. appreciate that.

#include <stdio.h> #include <stdlib.h>  void lerdeputados(int d) {     printf("indique o número de deputados repartir: ");     scanf("%d",&d); } int main(void) {     int d;     lerdeputados(d);     printf("%d",d);      return 0; } 

the problem here when pass variable d lerdeputados function, it's passed by value, means copied. value changed inside function, it's changing copy, , changing copy of course not change original.

what need here pass variable by reference. unfortunately c doesn't have that, can emulated using pointer. in other words, need pass pointer variable d lerdeputados function.

like

void lerdeputados(int *d) { ... } 

then call address-of operator:

lerdeputados(&d);
