int bin2dec(int decimal);

int main(void)
{
int num;

printf("The decimal equilavent is: %d", bin2dec(decimal));

getchar();
getchar();
return 0;
}

int bin2dec(int decimal)
{
int num[10];
int i;
int bin;
int arr1[10];
int arr2[10] = {512,256,128,64,32,16,8,4,2,1};

printf("Enter a binary(0's and 1's) number: ");
scanf("%d", &arr1);

This is qheere I get confused.
for (i = 0; i < arr1; i++)
{
if (arr1[i] == 1)
num[i] = arr1[i];
arr2[i]= num[i]
decimal = arr2[i];
}

return decimal;
}

2. A student studying Information Technology at Polytechnic of Namibia is examined by coursework and written examination. Both components of assessment carry a maximum of 50 marks. The following rules are used by examiners in order to pass or fail students. a. A student must score a total of 40% or more in order to pass (total = coursework marks + examination marks) b. A total mark of 39% is moderated to 40% c. Each component must be passed with a minimum mark of 20/50. 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.
