visual studio express complains missing ';' after type in c program

Question

What is the problem with my code?

#include

int main() {
    FILE *file;

    char string[32] = \"Teste de solução\";

I think Oli Charlesworth has given you the answer you need.

Here are some tips for you:

• If you use a backslash inside a string, you must put two backslashes.

• You should check the result of fopen(), and if it is NULL you should stop with an error.

• You should not specify the size of the array for your string; let the compiler count how many characters to allocate.

• In the for loop, you should not hard-code the size of the string; use sizeof() and let the compiler check the length, or else loop until you see the terminating nul byte. I suggest the latter.

Rewritten version:

#include
#include

int main() {
    FILE *file;
    int i;

    char string[] = "Teste de solução";

    file = fopen("C:\\tmp\\file.txt", "w");
    if (!file) {
        printf("error!\n");
    }

    printf("Digite um texto para gravar no arquivo: ");
    for(i = 0; string[i] != '\0'; i++) {
        putc(string[i], file);
    }

    fclose(file);

    return 0;
}
