c - Visual Studio Express提示缺少';'键入c程序后

我的代码有什么问题？

#include<stdio.h>
#include<string.h>

int main() {
    FILE *file;

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

    file = fopen("C:\file.txt", "w");

    printf("Digite um texto para gravar no arquivo: ");
    for(int i = 0; i < 32; i++) {
        putc(string[i], file);
    }

    fclose(file);

    return 0;
}

错误：

最佳答案

显然，您将其编译为C，而不是C ++。 VS不支持C99，在这种情况下，您可能不会这样做：

for (int i = 0; i < 32; i++)

您需要执行以下操作：

int i;

...

for(i = 0; i < 32; i++)

i的声明必须在函数中所有语句之前出现。
