Passing value structure

**ncode** · 11-16-2011

How do i pass a value from the main to a function which involved structure? I get always error. Please do help me to correct

Code:

#include<stdio.h>
	
	void PrintPhoneX (phone x.brand, phone x.model, phone x.price){
	printf("====Phone x====\n");
 	printf("Brand: %s\n Model: %s\n Price: %d\n",x.brand,x.model,x.price);	
	}
	
	void PrintPhoneY (phone y.brand, phone y.model, phone y.price){
	printf("====Phone y====\n");
	printf("Brand: %s\n Model: %s\n Price: %d\n",y.brand,y.model,y.price);	
	}
	
	
	void PrintPhoneZ (phone z.brand, phone z.model, phone z.price){
	printf("====Phone z====\n");
    printf("Brand: %s\n Model: %s\n Price: %d\n",z.brand,z.model,z.price);
	}
	

struct phone{
	char brand[10];
	char model[10];
	int  price;
};

int main (){
	struct phone x;
	struct phone y;
	struct phone z;
	
	printf("====Phone x====\n");
	printf("Brand:");
	scanf("%s",x.brand);
	printf("Model:");
	scanf("%s",x.model);
	printf("Price:");
	scanf("%d",&x.price);
	
	printf("====Phone y====\n");
	printf("Brand:");
	scanf("%s",y.brand);
	printf("Model:");
	scanf("%s",y.model);
	printf("Price:");
	scanf("%d",&y.price);
	
		
	printf("====Phone z====\n");
	printf("Brand:");
	scanf("%s",z.brand);
	printf("Model:");
	scanf("%s",z.model);
	printf("Price:");
	scanf("%d",&z.price);
	
	PrintPhoneX (phone x.brand, phone x.model, phone x.price);
	PrintPhoneY (phone y.brand, phone y.model, phone y.price);
	PrintPhoneZ (phone z.brand, phone z.model, phone z.price);
}

Something closer to this perhaps:

Code:

#include<stdio.h>

struct phone{
    char brand[10];
    char model[10];
    int  price;
};
     
void PrintPhone (struct phone temp){
    printf("====Phone====\n");
    printf("Brand: %s\n Model: %s\n Price: %d\n",temp.brand,temp.model,temp.price); 
}

int main (){
    struct phone x;
    struct phone y;
    struct phone z;
    
    ...
     
    PrintPhone(x);
    PrintPhone(y);
    PrintPhone(z);
}

The PrintPhone function has a struct phone parameter. This means that it has to know what a phone struct looks like... which means you need to put the definition of the phone struct before the code for the function so the compiler will see it and can understand what a phone struct is.

Your functions are all somewhat redundant. They all do the same thing with the data passed in so you really only need one function and just have to pass in the different variables x/y/z to that one function.
