unsigned long dec,rem,i=1;
unsigned long bin=0;//remember to set it to zero
cout<<"Enter a decimal number : ";
cin>>dec;
while(dec>0)
{
rem=dec%2;
dec=dec/2;
bin=bin+(i*rem);

If a student scores a total of 40% or more but does not achieve the minimum mark in either component he/she is given a technical fail of 39% (this mark is not moderated to 40%) d. Grades are awarded on marks that fall into the following categories. Mark 100-70 69-60 59-50 49-40 39-0 Grade A B C D E Write a program to input the marks for both components (coursework marks out of 50 and examination marks out of 50), out put the final mark and grade after any moderation.
