Answer 2

C does not allow us to declare variable anywhere apart the top of the function. So remove that line that says

int total = .....

Declare "total" at the top level of the function and use it like

total = "...."

Answer 3

In this code, input it correctly in 'scanf' according to the subjects, you total the marks of all the subject then use add operator '+' and then you can print the total marks of subjects.

Hint: Area of rectangle
Input the length of the rectangle
Input the width of the rectangle
Area of the rectangle formula: length * width
