Problem running C program [closed]

I am using Windows 10 OS. I installed MinGW for compiling C programs. I tried running my program using the gcc command on the Command Prompt. The file compiles and an executable file(.exe) is formed in the same folder as my source file. But when I try running this file, I keep getting the message ‘Access is denied’. Also the .exe file vanishes after this. I do not know what is wrong. Please help me out.

P.S Another time I did the same thing mentioned above and the .exe file ran and I was able to see the output on the Command line. And this time the .exe file did not vanish either.
