- Give an example of program that calculate the following sum:arrow_forwardWrite a program that receives a double value from the user, deducts 1 from it, and prints it with 3-digit precision. The program should continue until the user enters a negative number (e.g. -2) as input. Sample Input: 12.34567 11.587 14.57 -19.5 Sample Output: 11.346 10.587 13.570arrow_forwardQ1: A, B, C are three positive numbers (A<=B<=C). Given a list of seven numbers which are made of A, B, C, A+B, B+C, A+C, and A+B+C. Please find A, B and C use given seven numbers. Sample input: 2 2 11 4 9 7 9 Sample output: 2 2 7 You could use additional test case to test your program: Input: 41 19 22 38 22 19 3 Output: 3 19 19 Input: 148385247 819365820 793320372 26045448 122339799 670980573 697026021 Output: 26045448 122339799 670980573 Input: 326552445 762589144 699462434 63126710 436036699 372909989 389679155 Output: 63126710 326552445 372909989arrow_forward
- Write a program that will display a table of trigonometric functions: sin x, and tan x for x is from 0 to 20 degrees. The output should be: COS X, Angle in degrees sin x COS X tan x 1 1 0.0175 0.9998 0.0175 0.0349 0.9994 0.0349 20 0.3420 0.9397 0.3640 2.arrow_forwardPerform the following using DEV-C++ Show your solution Write a program that determines a student’s grade. It reads four test scores (between0 and 100) and calculates the grade based on the following rules: If the average score is 90 or more, the grade is ‘A’. If the average score is between 80 and 90, the grade is ‘B’. If the average score is between 70 and 80, the grade is ‘C’. If the average score is between 60 and 70, the grade is ‘D’. If the average score is less than 60, the grade is ‘F’.arrow_forward2. The total resistance of n resistors in parallel is: n 1 i=1 R; Suppose we have a network of two resistors with the values 400 2 and 200 Q. Then our equation would be: 1 1 R 400 ' 200 1 + and the total resistance of our two-resistor network is 133.3 N. Write a program to compute the total resistance for any number of parallel resistors.arrow_forward
- Write a program that takes as input a number of kilometers and prints the corresponding number of nautical miles. Use the following approximations. -A kilometer represents 1/10,000 of the distance between the north pole and equator. -there are 90° containing 60 minutes of arc each, between North Pole and equator -A nautical mile is one minute of an arcarrow_forwardWrite a Python (or R) program that asks the user to enter an integer (X), then: Determines if X is prime or not • If X is not prime, compute and print the factors of that integer X • Evaluate and print the equation Y=8X²+ 1, for X values from -5 to 5 using the range function and for looparrow_forward1. Write a program that asks the user to enter n and then it computes the value of the sum: 12 + 22+32 + +n? = Ei? ... check" whenn = 200, the answer shou; ld be 2686700 2. The total resistance of n resistors in parallel is: 1 = R Suppose we have a network of two resistors with the values 400 Q and 200 . Then our equation would be: 1 1 1 R 400 * 200 and the total resistance of our two-resistor network is 133.3 Q. Write a program to compute the total resistance for any number of parallel resistors.arrow_forward
- Write a program to enter a value of x and compute the value of y where if x ≥0 x -x - if x < 0arrow_forwardTwo cars A and B leave an intersection at the same time. Car A travels west at an average speed of x miles per hour and car B travels south at an average speed of y miles per hour. Write a program that prompts the user to enter the average speed of both the cars and the elapsed time (in hours and minutes) and outputs the (shortest) distance between the cars.arrow_forwardPlease write a program which asks the user for a number of days. The program then prints out the number of seconds in the amount of days given. The program should function as follows: How many days? 1 Seconds in that many days: 86400 Another example: How many days? 7 Seconds in that many days: 604800 1 2 Sample output Sample outputarrow_forward
