我已经在 vscode 中正确安装并运行了 c/c++，我的 gcc 版本是 8.2.0 并且我已经安装了 MinGw

我使用 VS code 来运行我的 C 程序

#include <stdio.h>
#include <stdlib.h>
#include <omp.h>

int main(int argc, char* argv[])
{
    int nthreads, tid;
    {
        tid = omp_get_thread_num();
        printf("welcome to GFG from thread = %d\n", tid);
        if (tid == 0){
            nthreads = omp_get_num_threads();
            printf("number of threads = %d\n", nthreads);
        }
    }
}

但这没有用，因为
