int main(int argc, char *argv[])
{
char *o;
int n1,n2;
o=argv[1];
n1= atoi(argv[2]);
n2= atoi(argv[3]);
printf("%d",n2);
if(strcmp(o,"add") == 0)
{
printf("%d",n1+n2);
}
else if(strcmp(o,"substract") == 0)
{
printf("%d",n1-n2);
}
else if(strcmp(o,"multiply") == 0)
{
printf("%d",n1*n2);
}
else if(strcmp(o,"devide") == 0)
{
printf("%d",n1/n2);
}
return 0;
}

Answer 1

ANGROSH ,
Unfortunately here on sololearn you can't pass command line arguments to the program (if somebody knows how, please correct me).
So you can't do: n = atoi(argv[2])...
this causes a segmentation fault because argv[2] and above doesn't exist.
Try your code on https://www.onlinegdb.com/ it will work... BTW if you expect command line arguments ALWAYS check that they're supplied by checking argc value.
