Thread: How I can fund out that what is going on inside of a varibale

I would like to print result in end of this function and see what is going on there. Please let me know how I can use printf here?

Thanks

Code:

Value *
stringToValue(char *val)
{
Value *result = (Value *) malloc(sizeof(Value));

switch(val[0])
{
case 'i':
result->dt = DT_INT;
result->v.intV = atoi(val + 1);
break;
case 'f':
result->dt = DT_FLOAT;
result->v.floatV = atof(val + 1);
break;
case 's':
result->dt = DT_STRING;
result->v.stringV = malloc(strlen(val));
strcpy(result->v.stringV, val + 1);
break;
case 'b':
result->dt = DT_BOOL;
result->v.boolV = (val[1] == 't') ? TRUE : FALSE;
break;
default:
result->dt = DT_INT;
result->v.intV = -1;
break;
}

return result;
}
