Can anyone help me with this code? it is not working, I can not find the error.
#include <stdio.h>
int chamar(int *n){
printf("Digite o valor de n:");
scanf("%d",&n);
printf("%d",n);
return 0;
}
int main(void){
int n;
chamar(n);
printf("\n%d\n",n);
}
To insert the value in the variable n into main , you must pass the memory address of it, and you do this in scanf :
chamar(&n);
In the method call, since the parameter is already a pointer, you do not need to pass the memory address of it, thus getting:
int chamar(int *n){
printf("Digite o valor de n:");
scanf("%d",n);
printf("%d",*n);
return 0;
}
It can be seen that% with% of% with% with% has n , printf is used to create a pointer and to get the value from inside the pointer, and chamar serves to get the memory address of the variable.
