A part of my code is to randomly generate an array with numbers between 0 and 999. I do this with a random number generator. However everytime it does it and returns the array, the intArray[8] to intArray[12] have what I presume is the address. How can I fix this. I have printed each part… Read More C Random Number generator returning address
So I already know how to open / read from a file line.. for example here’s what I wrote so far. a=0 file_paths = sys.argv[1:] for path in file_paths: a=1 if(a==0): while True: print(‘\nSpecify where the path of the code is’) print(‘Example /home/user/desktop/code.txt \n’) path=input(‘Input Here: ‘) if os.path.isfile(path)==True: break else: print(‘No files found.

My question is how can I split argv into two parts and store the parts in two variables. I want my program to get parameters then a delimiter and then again parameters like this: ./program parameter1 parameter2 \: parameter3 parameter4 As you can see, the escaped ‘:‘ will act like a delimiter, cutting the array… Read More How to split char pointer array into two char pointer arrays
