cin>>ca>>exam;
total=ca+exam;
switch(total){
case <=44:
grade='F';
break;
case >=45:
grade='D'
break;
and so on, but unfortunately its not working
please help me solve this problem

Answer 1

Faisal Hamman Adama Muhammad you cannot have case as condition...it must have value...I.e. case 4: not like case <4:

Answer 2

you can club cases if it's required as below to achieve the same:

case 1:
case 2:
case 3 :
case 4:
// do some stuff for case as 1 to 4

case 5:
//do stuff for case 5
default:
//do stuff for rest all scenario

Answer 3

i know that i omitted the cout but my main problem is the case

Answer 4

hi ,
Aren't cout<< or cin>> are missing after each case ?

Answer 5
