  5. Good evening, while i am running on cmd I am seeking the syntax error on main(). my code is as below: def main() : operation = input ("what do you wnt to do (+,-,*,/): ") if(operation != "+" and operation != "-" and operation != "*" and operation != "/"): #invalid operation print("You must enter a valiid operation") else: var1 = int(input("Enter num1: ")) var2 = int(input("Enter num2: ")) if(operation == "+"): print(add(var1, var2)) elif(operation == "-"): print(sub(var1, var2)) elif(operation == "*"): print(mul(var1, var2)) else: (print(div(var1, var2)) main()
  6. Hello, Can anyone point me to a C++ playlist intended for large, real-time embedded, safety-critical systems? I am an Ada software developer new to C++ and have found the YouTube playlist C++ Beginners Tutorials at kjd Electronics very helpful. Large, real-time embedded, safety-critical systems have particular issues. By large, real-time embedded I mean at least half a million lines of code running on multiple tasks at different rates. Different portions of vertical and lateral guidance software are time-sliced to run at 1, 5, 10 and 20 hertz. Flight planning software is time-sliced to run at 1 and 5 hertz. Navigation at 1, 5 and 10 hertz. These different software functions must share uncorrupted data with each other in this multi-task environment. Safety-critical means we can't just cycle power and try again when the system locks up. If the final system fails at 30,000 feet, then 200 people die and a $100 million plane crashes. You have to juggle phone calls from the next of kin, angry investors, insurance agencies, National Transportation Safety Board and their many, many lawyers. Undefined variables, unbounded arrays, divide by zero, and square root of negative numbers, etc. must be identified and eliminated during development. Then defensive code must still be written because we always assume we have missed some coding error. My industry is warming up to C++ code and so I need to learn it. Can anyone point me to a C++ playlist intended for large, real-time embedded, safety-critical systems?
  7. Hi Mohammad, I'm learning C++ too. I'm a beginner and I'm undergoing C++ Training in Chennai. How is the course going on? It was a bit difficult for me in the beginning. But now slowly I'm able to get the ideas. And I'm gathering a lot of information from here. Regards to you.
