C++ Programming
- Write a program to print Hello, World on the standard output.
- Write a program that uses the multiplication operator, *, to print the product.
- Program to use
a separate statement to print each operand. - Write a program that uses a while to sum the numbers from 50 to 100.
- write a while that prints the numbers from ten down to zero.
- Write a program that prompts the user for two integers. Print each number in the range specified by those two integers.
- What are the differences between int, long, long long, and short?
- To calculate a mortgage payment, what types would you use for the rate, principal, and payment? Explain why you selected each type.
- Determine the type of each of the following literals. Explain the differences among the literals in each of the four examples:
- What, if any, are the differences between the following definitions: int month = 9, day = 7; int month = 09, day = 07;
- What values do these literals represent? What type does each have? (a) “Who goes with F\145rgus?\012” (b) 3.14e1L (c) 1024f (d) 3.14L
- Using escape sequences, write a program to print 2M followed by a newline. Modify the program to print 2, then a tab, then an M, followed by a newline.
- Explain the following definitions. For those that are illegal, explain what’s wrong and how to correct it.
(a) std::cin >> int input_value;
(b) int i = { 3.14 };
(c) double salary = wage = 9999.99;
(d) int i = 3.14; - Write a program to calculate the highest two numbers in an array with length n, and print these numbers with their indexes.
- Write a C++ program to change every letter in a given string with the letter following it in the alphabet (i.e. a becomes b, p becomes q, z becomes a).
- Write a C++ program to find the largest word in a given string.
- Write a C++ program to count all the characters, blank spaces and words in a given string.
- Write a C++ program to find a word in a given string that has the highest number repeated letters.
Write a C++ program to find a word in a given string that has the highest number of repeated letters.
