error on declaring int

How can I declare ’M’?
There will be 2 errors if I write int M

• syntax error before int
• ‘m’ undeclared (first use in this fuction)

Here’s the code-

Code:

---

float calculate_quiz()
    {
          float quiz, total=0;
         
          for (m=0; m<3; m++)
          {
            printf("\nQuiz %d <5M>: ", (m+1));
            scanf("%f", &quiz[m]);
            total = total + quiz[m];
          }     
            return ((total/15)*10);
    }

---

Anyone can help out? thanks

The same way you declared quiz:

Code:

---

float calculate_quiz()
    {
          float quiz, total=0;
          int m;
          for (m=0; m<3; m++)

I think you might be declaring m inside the loop like this

Code:

---

for(int m=0;m<3;m++)

---

In this case the compiler throws an error(mine also). I think this is not the standard way to do. Is this so? If anybody could throw some light on this matter.
Also if i declare any variable at any place in main except immediately after the starting curly brace, it shows an error . Why is this so? Is it necessary to declare all the variables at one place just after the starting brace of main?

Code:

---

cc -std=c99 -Wall main.c -o test

---

ok
it is not conform to C89

Code:

---

‘for’ loop initial declaration used outside C99 mode
