Step-by-step solution
7 stepsHere are the solutions to the programming questions:
Part 3· 2 steps
Analyze the C code.
The program prompts the user to enter their name and the year they were born. It then calculates their current age in years, assuming the current year is 2024. It also calculates their age in months based on the calculated age in years.
State the program's design.
The program is designed to calculate and display a user's age in years and months based on their name and birth year input.
Part 4· 2 steps
Identify the required modification.
To implement the voting eligibility check, an
if-elsestatement needs to be added after theagecalculation to determine and print the appropriate message based on whetherageis less than 18.Provide the modified code.
#include <stdio.h> int main() { int BY, months, age; char name[15]; printf("\n Enter Your Name: "); scanf("%s", name); printf("\n Enter the year you were born: "); scanf("%d", &BY); age = 2024 - BY; months = age * 12; // Modified section for voting eligibility if (age < 18) { printf("\n You cannot Vote in Cameroon"); } else { printf("\n Congrats!! You Can Vote in Cameroon"); } printf("\n %s, You are %d years old", name, age); printf("\n You are %d months old", months); return 0; }
Part 5· 1 step
List two variables used in the program and their data types.
age:intname:chararray (specificallychar[15])
Part 6· 1 step
Identify the control structures.
In the original program, there are no explicit control structures; the code executes sequentially.
In the modified program (as per Question 4), theif-elsestatement is used, which is a selection or conditional control structure.
Part 7· 1 step
Describe the flowchart representation.
A flowchart for the modified program would include the following standard elements:
- Start/End: Oval shapes to indicate the beginning and end of the program.
- Input/Output: Parallelogram shapes for operations like
printf(displaying messages) andscanf(receiving user input for name and birth year). - Process: Rectangle shapes for calculations such as
age = 2024 - BYandmonths = age * 12. - Decision: A Diamond shape for the conditional check
age < 18. This diamond would have two outgoing paths: one for "True" (age is less than 18) and one for "False" (age is 18 or greater). - Flow Lines: Arrows connecting all symbols in the correct logical sequence, showing the direction of program flow. The paths from the decision diamond would converge before the final output statements and the End symbol.
