Answer 4

ohk. . :)

Answer 5

ok , I'm waiting . . . . . . .

Answer 6

we have to get the input as grade from the user for each course example mathematics, physics etc.??
Is it necessary to get input for each course?? well i mean to say the user maight not be taking all the courses. . or do we have to take input for all the courses??
secondly what does credit hour stands for?? How do we hv to use in the programme??

Answer 7

yes , we have to take input for all the courses
Mathematics 4 Physics 4 Chemistry 4 Computer 3 BEL 3
Total 18 credit hour stands

Answer 8

90 to 100 = A
80 to 89 = B
70 to 79 = c
60 to 69 = D
lessthen 60 = F

Answer 9

Since we dont have CGPA system in my country??
What is the formula to calculate it ??

Answer 10

Total grage divided by total credit hour

Answer 11

ohk so wht we will be doing here is to get the input as Grade from the user for each course and then finding out the total sum of the points. . and then divide it by the total sum of respective credit hour?? do i sound correct??

Answer 12

yes , extly right

Answer 13

ohk wait. . m trying :)

Answer 14

ok

Answer 15

For Example :
Mathematics = ( Gradre poin 2 ) ( Grade Hours 3 ) that means grade poin 2*3 = 6
Physics ( Gradre poin 3 ) ( Grade Hours 3 ) that means grade poin 3*3 = 9
Chemistry ( Gradre poin 2 ) ( Grade Hours 3 ) that means grade poin 2*3 = 6
here Total credit Hours 3+3+3 = 9 and Grade poin 6+9+6=21
So CGPA = 21/9

Answer 16

21/9 = 2.333

Answer 17

ohhh mistak not gradre hours its credit hours

Answer 18

ohk
but credit hours are given to us for each course
they r predefined. . we dont have to get them as input frm the user??

Answer 19

yes , credit hour is fixed , user can't input credit hours

Answer 20

ohk :)

Answer 21

For Mathematics 3 credit hours
Physics 3
Chemistry 3
Computer 3
BEL 3
Fixed

Answer 22

Answer 24

ohk

Answer 25

i need just the formate of the programe

Answer 26

ohk wait. . I will be doing it for maths and physics. . u will get the idea how to do the rest:)

Answer 27

ohkkkk ,

Answer 28

#include<stdio.h>
#include<conio.h>
void main()
{
int a=0, b=0;
float cgpa;
char m,bel,;
printf("Enter the grade obtained in Mathematics");
scanf("%c",&m);
if(m=='A')||(m=='a)
a=(a+4)*5
if(m=='B')||(m=='b')
a=(a+3)*5
if(m=='C')||(m=='c')
a=(a+2)*5
b=b+5
printf("Enter the grade obtained in BEL");
scanf("%c",&bel);
if(bel=='A')||(bel=='a)
a=(a+4)*3
if(bel=='B')||(bel=='b')
a=(a+3)*3
if(bel=='C')||(bel=='c')
a=(a+2)*3
b=b+3
cgpa=a/b
printf("The cgpa=%f",cgpa)
}



To make it clear. . i have used for BEL instead of physics . . coz it's credit hour is 3. . differnt frm physics n maths :p

Answer 57

Ahaan. . u r doing it in c++. . so u need to define header file
<iostream.h>. . standard input output
and not <stdio,h> (that's for c)
Moreover the code that u hv pasted is in c++
whereas the tyj.pnj is in c. .
Mate. . first make it clear in which language u wanna make uar programme
becoz uar logic is correct. . just the syntax prob
CHEERS

Answer 58

First i need c not c++ that means tyj.pnj

Answer 59

then paste the code in c. . and not c++ plz

Answer 60

ok

Answer 61

#include <stdio.h>

void main()

int roll;
char name[30];
float marks;
}student[5];
int i;

printf("Plz Enter the name,roll & marks of the students 1 by 1.");

for(i=0;i<5;i++)
{
scanf("%s %d %f",student[i].name,&student[i].roll,&student[i].marks);
}

printf("\n\n\tName \tRoll \tMarks");

for(i=0;i<5;i++)
{
printf("\n%d \t%s \t%d \t%f",i+1,student[i].name,student[i].roll,student[i].marks);
}
}

Answer 62

ERROR IN

for(i=0;i<5;i++)
{
scanf("%s %d %f",student[i].name,&student[i].roll,&student[i].marks);
}
IT SHOULD BE
scanf("%s %d %f",&student[i].name

u missed that &
