Strings and Structures

I have a structure with a string defined inside it, is there a way to change the string later in my program....

CODE....
//define structure
struct myStruct {
char name[40];
int age;
};

//function to fill array of structures with values
void fillArray(struct myStruct *);

int main(void){
//create array of structs
struct myStruct myStructArray[10];

//put values in array of structs
fillArray(&myStructArray);

//print name from struct
printf("%s", myStructArray[2].name);
}

//fills array with values
void fillArray(struct myStruct * workwithStruct){
workwithStruct[2].name = "JOHN";
return;
}


if i print the name inside the fillArray function it will print fine but when I return to the main function it prints garbage

I'm new to structs, Can someone please help me out?

workwithStruct[2].name = "JOHN";

This is wrong. You have to use something like strncpy to fill the string.

Furthermore, you're accessing your pointed to structure entirely incorrectly. That's not how you access members of a structure via a pointer.

Quzah.

I wonder how the previous code compiled : the argument passed to the function fillarray was of the wrong type. The operator = does not copy strings in C; you have to use the function strcpy.
It is a good idea to include the appropriate headers.

Code:

#include <stdio.h>
#include <string.h>


struct myStruct {
char name[40];
int age;
};

void fillArray(struct myStruct *);

int main(void){
struct myStruct myStructArray[10];
fillArray(myStructArray);
printf("%s", myStructArray[2].name); 
return 0;
}

void fillArray(struct myStruct * workwithStruct){
strcpy( (workwithStruct+2)->name,"JOHN");
return;
}

Thankyou, that was all the help i needed

I am new there was no reason to tear me down for doing it wrong, not everyone starts an expert!
