Pseudo code
/*
This is a pseudo code for calculating the GPA for students each registered for different no of courses */
CalculateStdntGpa (int NoStudents, int NoCourses, char StudentNames[],char CourseGrade[])
//INPUT: No of students, Name of students, No of courses and Grades for each course
//OUTPUT: The GPA for each student

for(int i = 0: i < NoStudents: i++){ StudentNames[i] <- StdntName; for(int j=1: j<= NoCourses: j++){ if(CourseGrade = ”A”){ GradePoint <- 4; } if(CourseGrade = ”B”){ GradePoint <- 3; } if(CourseGrade = ”C”){ GradePoint <- 2; } if(CourseGrade = ”D”){ GradePoint <- 1; } if(CourseGrade = ”F”){ GradePoint <- 0; }

GradePoints[j-1] <- GradePoint; } Return GPA
}

1. Analysis
The following is a brief analysis of the program being built * Inputs
The inputs for the program are: I. No of students which should be an integer value to hold the number of students II. Names for students which would be an array structure to hold all student names. This array would be of data type character III. No of courses for each student which is of data type integer IV. Grade for each course registered by each student which is an array of data type character

* Data processing
The program takes the inputs discussed in details above and processes them by evaluating the value of each respective grade using for-loops, after which summation is done to find the GPA for each student by dividing the total values for grades by the number of courses registered by each student. * Outputs
The expected outcome for the program is the Average Grade Points for each student which is the GPA whose data type would be appropriate as double since it’s an average of the total grade values for each course registered by a student. * Variable definitions
The data types for data to be processed by the program include I. Integer: these include the no of students, No of courses registered by each student II. Double: include data like the average GPA points for each student III. Character: include data like the students’ name and Grades

* Formulas and sample calculations
Mainly the formula for calculating average is essential here as the average of GPA points is necessary:
GPA = (p1 + p2 + P3)/3 where p is the points
