How to fill an array of structures in C

[stamatiou]

Hey guys,
I have a structure and an array

struct identity
{
char name[10];
char secondname[10];
int age;
}humans[100];

Now, how can I fill all the contents of the array with a for loop?

int i = 4;
humans[i].age = 33;


sets one part of one entry. Go from there.

int i = 4;
humans[i].age = 33;
sets one part of one entry. Go from there.

for(i = 0;i<=10;i++) {
human[i].name = "Name";
human[i].age = 30;
}
Would this work?

[slavik]

for(i = 0;i<=10;i++) {
human[i].name = "Name";
human[i].age = 30;
}
Would this work?
No, go read about strings in C.

[Arndt]

for(i = 0;i<=10;i++) {
human[i].name = "Name";
human[i].age = 30;
}

What values will i take in this loop? What indices of 'human' are valid?

I don't recommend using that code. As Slavik points out, you can't assign a string like that to a character array. You will need to use a C standard function like strncpy() to copy the string to your variable. You would decide how many elements are in your array of structures when you declare your variables. I recommend looking into how C strings work, how arrays work and how 'for' loops work before moving into structures. If you know how to populate an array with a for loop then you won't have to ask us how to populate a structure that way.
