[40 Marks total. Writing a program that generates an accurate output in A and C 20 marks. Analysis of the problem i.e. data requirements 6 marks. Good programming practice i.e proper use of remarks and structuring of the program modules 4 marks. Algorithm proposed in B 10 marks] A. [15 marks] Write a program that generates the positions of whitespaces in a string and prints them on the screen. For example given the following string as input: hello there my friends the program should generate: 5, 11, 14 B. [10 marks] Propose an algorithm to extract the tokens (words) from a string. Words are supposed to be separated by white spaces. C. [15 marks] Write a program that extracts the tokens from a string. Given a string as input, the program should print on the screen each token on a new line. For example given the following string as input: hello there my friends the program should generate: hello there my friends For each questions A and C in this task, first provide the analysis of the problem by clarifying the inputs, outputs and the data requirements. Then write the program and submit the source code as part of the assignment. It is important to clearly structure your program by using indentation and comments to clarify your ideas.
