Unable to do SSH using Command Promp \

Question

I am trying to establish SSH connection to a remote server to execute some command. I require to take CLA in my final program, so I'm trying to execute from Command Prompt. A sample code is given

#include <stdio.h>
#define PATH_MAX 128

int main(void){

    FILE *fp;
    char path[PATH_MAX];

    fp = popen("ssh user@HOST \"command\"", "r");
    if (fp == NULL)
       /* Handle error */;

    while (fgets(path, PATH_MAX, fp) != NULL)
    printf("%s", path);
    fclose(fp);
    return 0;
}

The code execute fine using DevC++ but when I execute same from Command prompt it does not execute giving following message "'ssh' is not recognized as an internal or external command, operable program or batch file." I tried both system("some command") and popen(). Both work fine in DevC but give same message when executed from Command Prompt. I'm having MinGW installed gcc version 8.2.0 (MinGW.org GCC-8.2.0-3)

SSH.exe needs to be in the Windows PATH. When the program is running, it might not be running under your profile.

It is possibly running under a system profile that does not have the same PATH defined. You could have the program check and/or update the PATH or have it run under your profile specifically.
