[QUOTE="yrollgayanth, post: 7596796, member: 121733"] Machan here is a part of the code, but this is done by java. U can use same method in C++ by changing few syntax. i'll put the rest soon [CODE]package average; import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); double T1, T2, T3, T4; // Test 1 of 30% System.out.print("Please enter test 1 marks :"); T1 = in.nextDouble(); while (T1 > 100 || T1 < 0) { System.out.print("Invalid.Please re-enter test 1 marks :"); T1 = in.nextDouble(); } // Test 2 of 30% System.out.print("Please enter test 2 marks :"); T2 = in.nextDouble(); while (T2 > 100 || T2 < 0) { System.out.print("Invalid.Please re-enter test 2 marks :"); T2 = in.nextDouble(); } //Test 3 of 30% System.out.print("Please enter test 3 marks :"); T3 = in.nextDouble(); while (T3 > 100 || T3 < 0) { System.out.print("Invalid.Please re-enter test 3 marks :"); T3 = in.nextDouble(); } //Test 4 of 30% System.out.print("Please enter test 4 marks :"); T4 = in.nextDouble(); while (T4 > 100 || T4 < 0) { System.out.print("Invalid.Please re-enter test 4 marks :"); T4 = in.nextDouble(); } // Calculate the final for 1st four tests double final1 = ((T1 + T2 + T3 + T4) / 4) * 0.3; System.out.println("Grade from first 4 tests:" + final1 + "%"); // Mid term test System.out.print("Please enter mid-term test marks :"); double midT = in.nextDouble(); while (midT > 100 || midT < 0) { System.out.print("Invalid.Please re-enter mid-term marks :"); midT = in.nextDouble(); } double midTper = midT * 0.2; System.out.println("Mid term test percentage:" + midTper); // Final term test System.out.print("Please enter final test marks :"); double finalT = in.nextDouble(); while (finalT > 100 || finalT < 0) { System.out.print("Invalid.Please re-enter final tests marks :"); } double finalper = finalT * 0.2; System.out.print("Final test percentage :" + finalper); } } [/CODE] [/QUOTE]
