Flowcharts are used as a prototype of an actual program.
First, I will write out the algorithm; which will be used as an explanation of the flowchart (see attachment for flowchart)
The algorithm is as follows;
1. Start
2. Get input for cost of a meal and cost of a drink;
3. Calculate the total cost for a meal and two drinks
4. Multiply the total cost of a meal and two drinks by 7, to get the weekly cost
5. Display the weekly cost
6. Stop
At the end of the algorithm/flowchart, the weekly cost is calculated and printed.
