how to assign a value to a string array?

Question

for example

#include 
#include 
#include 

char substr[10][20];

int main() {
    substr[0] = \"abc\";

I hate giving 'full' answers to homework questions, but the only way to answer your question is to show you the answer to your problem, because it is so basic:

#include 
#include 

#define MAXLEN 20

char substr[10][MAXLEN];

int main(void) {
        strncpy(substr[0], "abc", MAXLEN);
        puts(substr[0]);
        return 0;
}

Your code (as is) has several faults:

• You are treating substr[0] as a string literal. You can't do that.
• You were using printf formatters incorrectly. %s is for strings
• You don't need to bother printf() to print a string
• You should (in real code) watch out for buffer overflows, hence strncpy()
• If main() doesn't want / need argc and argv, its arguments should be void
• main() should return a value, as its return type is int
• You aren't using anything out of , why include it?

I suggest researching string literals, the functions available in as well as format specifiers.

Also note, I am not checking the return of strncpy(), which is something you should be doing. That is left as an exercise for the reader.
