Sorry if this post comes off as ignorant, but I\'m still very new to C, so I don\'t have a great understanding of it. Right now I\'m trying to figure out pointers.
I mad
To make it work rewrite the code as follows -
#include
int change(int * b){
* b = 4;
return 0;
}
int main(){
int b = 6; //variable type of b is 'int' not 'int *'
change(&b);//Instead of b the address of b is passed
printf("%d", b);
return 0;
}
The code above will work.
In C, when you wish to change the value of a variable in a function, you "pass the Variable into the function by Reference". You can read more about this here - Pass by Reference
Now the error means that you are trying to store an integer into a variable that is a pointer, without typecasting. You can make this error go away by changing that line as follows (But the program won't work because the logic will still be wrong )
int * b = (int *)6; //This is typecasting int into type (int *)
