(penalty of usage pow function is -30p) b-You can use sqrt function for sequare root 3- [20p] According to folowing stepts Draw the flow chart[10p] and write the c code [10p] 1. Start 2. Sum=0 3. k=1 4. read a value from use from user which is "V" 5. If v is greater or equal to "1" AND k is less than v, repeat following sub steps 5.1 Sum = Sum + k 5.2 k=k+2 6. Output the sum 7. Stop
