Write a C++ program to display the pattern to display the following pattern using an asterisk. eg. User input half of the diamond: 5 Output:

Write a program in C to convert an infix expression to a postfix expression and use it to evaluate a mathematical expression entered by a user. If a user enters the following formula: 2 + ((8 + 12) / 10 - 3) * 5 , the output would be -3.

Can you help me a C++ Program to do the following: Create a program that reads a simple arithmetic expression andevaluates it. More precisely, the program reads from the user a line oftext that’s supposed to contain two numbers separated by an arithmeticoperator, as in35.6 + 12The program then prints back the expression and its value, as in35.6 + 12 = 47.6The program should verify that the input line contains two numbers, oneoperator and nothing else. There can be whitespace before the first number, after the second number and between each number and the operator.The operator can be either +, −, * or /. In case of an error, the programshould print Invalid expression and quit.When the program prints the expression, there should be no whitespacebefore the first number and there should be exactly one blank space beforeand after the operator and the equal sign.Use string streams.

"C Language only" 4. userinput Program 4 will accept alphabetic input from the user via stdin change it to all capital letters and print it to the screen. Do not ask the user to enter the input. Assume the user will know to input alphabetic input. Usage would be: userinput
