Introduction to Programming with C++
- (Count the letters in a string) Write a function that counts the number of letters in a string using the following header: def countLetters(s) : Write a test program that prompts the user to enter a string and displays the number of letters in the string. the answer should be in python.arrow_forward(Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the following 2 x 2 system of linear equation: ax + by = e ed – bf af- ec ad - bc cx + dy = f ad – bc y = Write a program that prompts the user to enter a and f and display the result. If ad - bc is 0 b, c, d , e, , report that The equation has no solution.arrow_forward(Financials: currency exchange) Write a program that prompts the user to enter the exchange rate from currency in U.S. dollars to Rupees PKR. Prompt the user to enter 0 to convert from U.S. dollars to Rupees PKR and 1 to convert from Rupees PKR and U.S. dollars. Prompt the user to enter the amount in U.S. dollars or Rupees PKR to convert it to Rupees PKR or U.S. dollars, respectively. Use c++ program.arrow_forward
- (Financial application: payroll) Write a Java program that reads the following information and prints a payroll statement:arrow_forward6. (Geometry: area of a pentagon) The area of a pentagon can be computed using the following formula (s is the length of a side): Area 5x s² 4 X tan TT 5 Write a program that prompts the user to enter the side of a pentagon and displays the area. Here is a sample run: Enter the side: 5.5 Enter The area of the pentagon is 53.04444136781625arrow_forward(Bar-Chart Printing Program) One interesting application of computers is drawing graphsand bar charts. Write a program that reads five numbers (each between 1 and 30). For each numberread, your program should print a line containing that number of adjacent asterisks. For example,if your program reads the number seven, it should print *******.arrow_forward
- (Area of a convex polygon) A polygon is convex if it contains any line segment that connects two points of the polygon. Write a program that prompts the user to enter the number of points in a convex polygon, then enter the points clockwise, and display the area of the polygon. Sample Run Enter the number of points: 7 Enter the coordinates of the points: -12 0 -8.5 10 0 11.4 5.5 7.8 6 -5.5 0 -7 -3.5 -5.5 The total area is 244.575arrow_forward(True or False) Seven different positive integers are randomly chosen between 1 and 2022 (including 1 and 2022).There must be a pair of these integers has a difference that is a multiple of 6.arrow_forward(Algebra: solve 2 * 2 linear equations) A linear equation can be solved using Cramer’s rule given in Programming Exercise 1.13. Write a program that prompts the user to enter a, b, c, d, e, and f and displays the result. If ad - bc is 0, report that “The equation has no solution.”arrow_forward
- (Algebra: solve 2 x 2 linear equations) You can use Cramer's rule to solve the following 2 X 2 system of linear equation: ed – bf ax + by = e cx + dy = f af - eс y ad – bc %3D ad – bc Write a program that prompts the user to enter a, b, c, d, e, and f, and displays the result. If ad – bc is 0, report that "The equation has no solution."arrow_forward(Sort three numbers) Write the following function to display three numbers in increasing order: def displaySortedNumbers(num1, num2, num3): Write a test program that prompts the user to enter three numbers and invokes the function to display them in increasing order. Here are some sample runs:arrow_forward(Sum the digits in an integer) Write a program that reads an integer between 0 and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all its digits is 14.arrow_forward
