How do you calculate cgpa using c plus plus program?

Answer 1

#include <stdio.h>

void main()

{

int num,num1,num2, cal;

num=cal=0;

char grade1=cal=0,grade2=cal=0;

printf("\n Enter the number of subjects taken in Spring Semester:");

scanf("%d", &num);

fflush(stdin);//

if(grade1==4){

printf("\n\nEnter the Math Grade(A,B,C): %c",grade1);

do{

printf("\ngrade1=");

scanf("%d",&cal);

}

else if(

printf("\nError!\n\n");

}while(1);

printf("\nEnter the Math Credit hours(1~3):");

num1 = getchar();

grade1=4;

}

else if(grade2==3){

grade2=3;

}

printf("\nEnter the Math Grade(A,B,C):\n");

scanf("%c",&grade1);

printf("Enter the Physics Grade(A,B,C):");

grade2 = getchar();

printf("\nEnter the Physics Credit hours(1~3):");

num2 = getchar();

printf("\nMath Credit hours: %d",num1);

printf("\nPhysics Grade: %c",grade2);

printf("\nPhysics Credit hours:%d\n",num2);

printf("\n <Math Credit hours> \n");

do{

printf("\n 1 + 1 = ");

scanf("%d", &cal);

}while(cal != 3);

printf("\n Error!\n\n");

}

printf("\n <Physics Credit hours> \n");

do{

printf("\n 4 - 1 = ");

scanf("%d", &cal);

}while(cal != 3);

printf("\n Error!\n");

}

printf("\n The End.\n");

system("pause");

}

Answer 3

CGPA is calculated the same as GPA. Whereas GPA covers one academic term (whether semester, trimester or quadmester), CGPA covers all academic terms.

To calculate the GPA, take the sum of the products for the term and divide by the total credit hours for that term.

To calculate the CGPA, take the sum of the products for all terms and divide by the total credit hours for those terms.

The product is the quality points for each subject multiplied by the credit hours for that subject.

Quality points are determined by the grade (A+, A, A-, B+, etc) while the grade is determined by the percentage mark. How the grades and quality points are determined from the mark can vary from institution to institution or country to country.

Working from the grades alone is often the simplest option, as an A+ always equates to 4.00 quality points, an A to 3.67 and an A- to 3.33. Each subsequent grade is worth 1/3 less than the previous grade. Although a C, D or E is typically a fail, the quality points are still valid for GPA/CGPA calculations.

There are various ways to convert grades to quality points but one of the simplest to implement is a lookup table where grades are mapped to values in the range 0.00 to 4.00.

Armed with this information it will be possible to write a C++ program to calculate GPA and/or CGPA, where the user simply selects the grade and credit hours for each unit in the academic term and/or terms.
