VScode debugger not working ( Warning: Debuggee TargetArchitecture not detected, assuming x86_64 )

I'm playing with VScode and I just can't get to figure out how to make the debugger work.

    Warning: Debuggee TargetArchitecture not detected, assuming x86_64.

Whenever I try to debug any codes, this error message comes up on the Debug console.

    {
        "name": "(gdb) Launch",
        "type": "cppdbg",

        "program": "${workspaceFolder}/file_name.exe",

                "ignoreFailures": true
            }
        ]
    }
]

This is my launch.json file,

{
// See https://go.microsoft.com/fwlink/?LinkId=733558
// for the documentation about the tasks.json format
"version": "2.0.0",
"tasks": [
    {
        "label": "build",
        "type": "shell",
        "command": "gcc",
        "args": [
            "file_name.c",
            "-o",
            "file_name.exe"
        ],
        "group": {
            "kind": "build",
            "isDefault": true
        },
        "presentation": {
            "reveal": "silent"
        },
        "problemMatcher": "$msCompile"
    }
]

and this is what my tasks.json file looks like.

I just got into programming and working with these json configuration files are really frustrating, any help would be appreciated.
