Ex 6) Devise an algorithm to receive a positive number, n, and output all prime numbers that are smaller than n and have a digit 7. For example, if n is 100, the program should output 7, 17, 37, 47, 67, 71, 73, 79, and 97. Your solution should have a main algorithm and two sub-algorithms, let's call them prime (num) and has 7 (num). You may reuse the prime sub-algorithm of Ex 5. You do not need to verify (e.g. by tracing) it though because you did it in Ex 5. You need to trace your has 7 algorithm. You should provide pre- and post-conditions for all your 3 (sub)algorithms.
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
I want answer to ex6, and give me a flowchart that should look like the one given in ex5. Please give me visual flowchart and not a written one. Thank you.
