Hello, i am very new to coding in c, but i am getting an error message in c and i dont know why-CodePudding

#include <stdio.h>
int main(){
    int number[];
    scanf("%d", &number);
    int counter = 0;
    while (counter < number){
        printf("%d\n", counter);
        counter  = 1;
    }
}

I am getting an error saying that an integer cant be compared with a pointer but im not sure how to fix it and dont understand why it doesnt work,.

type here

CodePudding user response：

This declaration of an array of incomplete type

int number[];

is invalid.

Just declare an object of the type int like

int number;

There is no any need to declare an array.

Instead of the while loop

int counter = 0;
while (counter < number){
    printf("%d\n", counter);
    counter  = 1;
}

it is better to use for loop like

for ( int counter = 0; counter < number;   counter ){
    printf("%d\n", counter);
}

because the variable counter is used only in the scope of the loop.

CodePudding user response：

yes you declare as array number this declare as integer because array access as a pointer varible . whole colde is

int number[];

replace with

int number;

whole code is:

 #include <stdio.h>
int main(){
    int number;
    scanf("%d", &number);
    int counter = 0;
    while (counter < number){
        printf("%d\n", counter);
        counter  = 1;
    }
}
