![### Understanding the Runtime Environment of a C Program
#### Problem Description:
**7.2 Draw a possible organization for the runtime environment of the following C program, similar to that of Figure 7.4 (Page 354).**
**a. After entry into block A in function f.**
**b. After entry into block B in function g.**
The given C program structure is as follows:
```c
int a[10];
char *s = "hello";
int f(int i, int b[]) {
int j = i;
A: { int i = j;
char c = b[i];
...
}
return 0;
}
void g(char *s) {
char c = s[0];
B: { int a[5];
...
}
}
int main() {
int x = 1;
x = f(x, a);
g(s);
return 0;
}
```
#### Detailed Explanation:
1. **Global Variables:**
- `int a[10];`: This is an array of 10 integers.
- `char *s = "hello";`: This is a pointer to a character array (string) initialized with "hello".
2. **Function `f`:**
- **Parameters:**
- `int i`: An integer parameter.
- `int b[]`: An array parameter.
- **Local Variables:**
- `int j`: Initialized to the value of `i`.
- **Block A:**
- `int i`: A new integer variable local to block A, initialized to `j`.
- `char c`: Stores the value from the array `b` at index `i`.
3. **Function `g`:**
- **Parameters:**
- `char *s`: A pointer to a character array.
- **Local Variables:**
- `char c`: Initialized to the first character of the string pointed to by `s`.
- **Block B:**
- `int a[5]`: An array of 5 integers, local to block B in function `g`.
4. **Function `main`:**
- **Local Variables:**
- `int x = 1;`: Initializes `x` to 1.
- Calls `f(x, a);`: The function `f` is called with `x` and](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce5cea56-9cd3-471d-b739-11e3ad279d5e%2F2f0df55c-2b25-44f9-a63f-4e6630c5a4a3%2Fc3ysloa_processed.jpeg&w=3840&q=75)
