Question

How design a C program to calculate the tuition payable by its students. The
program should accept the students Id number, name, Programme being persued and the programme
Year (1, 2, OR 3) the student is in, and the students GPA (NB* First year students start with a GPA of
0 and the program is to programmatically insert this value). The regular tuition fee for all students is
$175,000.00. However, a discount is given to every student whose GPA falls within a certain range,
based on whether the student is in Year 1, Year 2, OR Year 3, as follows:
Year GPA Discount
1 0 0%
2 2.7 to 4.0 10%
3 3.2 to 4.0 15%
The program is to calculate the final tuition amount, and display the students’ name, Id number,
programme being persued, regular tuition, discount amount and final tuition amount, for each student
processed. After each student is processed, the system should give the user an option to process
another.

Here is the program for your question in C Programming Language.

CODE :(filename.c)

#include<stdio.h> int main() {    //Variables decleration    int studentId,year;       char studentName[100],programme[100],choice[3];       float GPA;       double tutionFee ;       //do while to ask user, after completeing one student record, to continue or not           do{    tutionFee = 175000;    //Reading values from user    printf("Welcome to ABC Tution System");       printf("\nPlease enter student's Id number : ");       scanf("%d",&studentId);       printf("\nPlease enter student's name : ");       scanf("%s",studentName);       printf("\nPlease enter student's programme : ");       scanf("%s",programme);       printf("\nPlease enter student's year : ");       scanf("%d",&year);       //validations for year    do{           if(year == 1)        {            GPA = 0.0;        }        else if(year == 2 || year == 3)        {            printf("\nPlease enter student's GPA : ");            scanf("%f",&GPA);            while(GPA < 0 || GPA > 5.00)            {                printf("Invalid GPA entered...Please enter GPA again");                scanf("%f",&GPA);            }                   }        else        {            printf("Invalid Year value given...Please enter year again(Only 1 or 2 or 3)");              scanf("%d",&year);                printf("\nPlease enter student's GPA : ");            scanf("%f",&GPA);            while(GPA < 0 || GPA > 5.00)            {                printf("Invalid GPA entered...Please enter GPA again");                scanf("%f",&GPA);            }                   }    }while(year!=1 &&year !=2 && year !=3);       //Calculating tution fee    if(year == 2)    {        if(GPA >=2.7 && GPA <= 4.0)        {            tutionFee = 175000 - (175000 * (0.1));        }    }    else if(year == 3)    {        if(GPA >=3.2 && GPA <= 4.0)        {            tutionFee = 175000 - (175000 * (0.2));        }    }       //Printing details    printf("\n\n The tution fee details of the student are :\n\nStudent ID : %d\nStudent Name : ",studentId);       puts(studentName);       printf("Programe Pursuing : %s",programme);          printf("\nYear : %d\nGPA : %.1f\nRegular Fee : $175,000.00",year,GPA);       if(year == 2)    {        if(GPA >=2.7 && GPA <= 4.0)        {            printf("\nDiscount : 10%% \nFinal Tution Fee : %.2lf",tutionFee);        }        else        {            printf("\nDiscount : 0%% \nFinal Tution Fee : %.2lf",tutionFee);        }    }    else if(year == 3)    {        if(GPA >=3.2 && GPA <= 4.0)        {            printf("\nDiscount : 20%% \nFinal Tution Fee : %.2lf",tutionFee);        }            else        {            printf("\nDiscount : 0%% \nFinal Tution Fee : %.2lf",tutionFee);        }    }    else    {            printf("\nDiscount : 0%% \nFinal Tution Fee : %.2lf",tutionFee);    }    printf("\nDo you want to get another student's fee ?(Y/N)");    scanf("%s",choice);    }while(strcmp(choice,"y")==0 || strcmp(choice,"Y")==0);    return 0; }

OUTPUT

If wrong input given

NOTE : As I have used scanf for reading strings please be careful while giving names of student and program , make sure they do not contain spaces if they contain spaces the second string after space will be taken as next variable value.

Any doubts can be explained with pleasure :)
