How to print array with looping with C

Question

I want to make programs that request integer input from the user. if the user enters 0, it will display "Sunday", if the user enters 1, the program will display "Monday" and so on until "Saturday". If the user enters a value outside the range 0 to 6, the program writes "Invalid Days". but when I input a integer the array of days didnt show up. What should I do ?

This is "code.cpp"

main(){
    char days[7] = {"Sunday","Monday","Tuesdat","Wednesday","Thursday","Friday","Saturday"};
    
    int i;
    
    printf("Input Integer:");
    scanf("%d",&i);
    
    if(i < 0 || i >= 7) {
      printf("invalid days\n");
      return;
    }    

    for (i ; i < 7;i++)
    {
        printf("Days: %d\n", days[i]);
    }
}

When i run it at dev C++ it show error,

4 91 F:\IPB\PENUGASAN\MATKUL\MATERI - Copy\APLIKOM\C++\UAS\UAS 2.cpp [Error] too many initializers for 'char [7]'

13 7 F:\IPB\PENUGASAN\MATKUL\MATERI - Copy\APLIKOM\C++\UAS\UAS 2.cpp [Error] return-statement with no value, in function returning 'int' [-fpermissive]

Why have you named a file with a C program with `.cpp`? Are you compiling this with a C++ compiler? — cigien, Dec 14 '20 at 01:45
don't use `i <= 7` but instead use `i < 7` as you only have 6 (counting from 0 days). — SSpoke, Dec 14 '20 at 01:47
`'Sunday'` [is not](https://stackoverflow.com/questions/3960954/multicharacter-literal-in-c-and-c) what you think it is. — Igor Tandetnik, Dec 14 '20 at 01:48
There are a lot of errors, you can start where the compiler suggested "too many initializers for 'char [7]'", you allocated 7 characters and is initializing with 7 strings — Matheus Rossi Saciotto, Dec 14 '20 at 02:12

    #include <stdio.h>

main(){
    char* days[7] = {"Sunday","Monday","Tuesdat","Wednesday","Thursday","Friday","Saturday"};
    
    int i;
    
    printf("Input Integer:");
    scanf("%d",&i);
    
    if(i < 0 || i >= 7) {
      printf("invalid days\n");
      return 0;
    }    

    for (i ; i < 7;i++)
    {
        printf("Days: %s\n", days[i]);
    }
}

Have you actually run this? What did it print? – Igor Tandetnik Dec 14 '20 at 01:49
Didn't run it but the code looks good it's a simple question. – SSpoke Dec 14 '20 at 01:49

Well, run it, see what it does print. – Igor Tandetnik Dec 14 '20 at 01:50
Don't have a compiler can't run it, tell me whats wrong with it? – SSpoke Dec 14 '20 at 01:51

ahh Multi-quotes not there eh?, finished should be good now – SSpoke Dec 14 '20 at 01:53

Please test the code you use in an answer, or at least mention that you have not tested the code in the answer itself. Also, in any case, you need to explain why and how the shown code solves the OP's problem. – cigien Dec 14 '20 at 01:57
char days[7]? that's just a string, not an array of strings – Eduardo Pascual Aseff Dec 14 '20 at 01:57
