无法在Visual Studio 2019中启动程序

Question

我一直在使用Visual Studio来分配编程类的作业，但收到错误消息“无法启动程序-系统找不到指定的文件”。我检查了一些针对此错误的解决方案，并尝试对其进行测试，但没有一个解决方案。也许我的编码有问题。这是代码（尚未完成）：

#define _CRT_SECURE_NO_WARNINGS
#define PI=3.1415
#include <stdio.h>
#include <math.h>
#include <conio.h>

/**************************************************************************

****************************************************************************/
void display_myInfo() {
    printf("\n**********************************");
    printf("\n*   CNIT 105 Assignment_5        *");
    printf("\n*  xxxxxxxxxxxxxxxx              *");
    printf("\n*   xxxxxxxxxxxx@xx.edu          *");
    printf("\n*   Lab section = Fri. 11:30     *");
    printf("\n**********************************");
}

    }
}

        printf("The input numbers do not form a triangle");
}
else {

Area = sqrt(S * (S - a) * (S - b) * (S - c));
return area;
}

int main() {
    float radius;
    float height;
    float area;
    float S;

    int display_myInfo();

}

有人可以帮助我解决此错误吗？ 谢谢。
