undefined Solution (a) Program Plan: Temp1 and temp2 variables are used in the program. Program Description: The main purpose of the program is to prompt the user to enter the two temperature value in integer. When both the values are equal then display the temperature. When both the values are not equal then do nothing. Program: //including essential header file #include <iostream> //using standard namespace usingnamespacestd; //main function intmain() { //variable declaration int temp1, temp2; //prompt the user to enter the first temperature cout<<"Enter the first temperature value in integer: "; //get the first temperature from the user cin>> temp1; //prompt the user to enter the second temperature cout<<"Enter the second temperature value in integer: "; //get the second temperature from the user cin>> temp2; //when both the temperature values are equal if (temp1 == temp2) { //display the temperature cout<<"Temperature is "<< temp1; } return 0; } Explanation: In the above program twointeger typevariable named temp1 and temp2is used to store the temperature entered by the user. Prompt the user to enter the two temperature values in the integer. Store both the values in the integer variable named temp1 and temp2. When both the temperature values are equal then display the temperature. Else do nothing. Sample Output: (b) Program Plan: letter 1and letter2 variables are used in the program. Program Description: The main purpose of the program is to prompt the user to enter the two character values in uppercase letters. Store both the values in the variable named letter1andletter2. Display both the letters in the alphabetical order. Program: //including essential header file #include <iostream> //using standard namespace usingnamespacestd; //main function intmain() { //variable declaration char letter1, letter2; //prompt the user to enter the first character cout<<"Enter the first character value in an uppercase letter: "; //get the first character from the user cin>> letter1; //prompt the user to enter the second character cout<<"Enter the second character value in an uppercase letter: "; //get the second character from the user cin>> letter2; //when the first letter is greater if (letter1 > letter2) { //display the letter in the alphabetical order cout<<"The letter in the alphabetical order is "<< letter2 <<" "<< letter1; } //when the second letter is greater or equal to the first letter else { //display the temperature cout<<"The letter in the alphabetical order is "<< letter1 <<" "<< letter2; } return 0; } Explanation: In the above program two character type variable named letter1 and letter2 is used to store the uppercase letters entered by the user. Prompt the user to enter the two alphabetic letter in the uppercase. Store the user entered character values in the character variable named letter1 and letter2. Using the IF ELSE statement display the upper case letter in the alphabetical order. Sample Output: (c) Program Plan: num1, num2,and num3 variables are used in the program. Program Description: The main purpose of the program is to prompt the user to enter the three integer type values. Store the values in the variable named num1, num2,and num3. Display the integer values in the decreasing order. Program: //including essential header file #include <iostream> //using standard namespace usingnamespacestd; //main function intmain() { //variable declaration int num1, num2, num3; //prompt the user to enter the first number cout<<"Enter the first number: "; //get the first number from the user cin>> num1; //prompt the user to enter the second number cout<<"Enter the second number: "; //get the second number from the user cin>> num2; //prompt the user to enter the third number cout<<"Enter the third number: "; //get the third number from the user cin>> num3; //using the else if statement //arrange the number in decreasing order if (num1 > num2 && num2 > num3) { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num1 <<" "<< num2 <<" "<< num3; } elseif (num1 < num3 && num1 > num2) { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num3 <<" "<< num1 <<" "<< num2; } elseif (num2 > num1 && num1 > num3) { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num2 <<" "<< num1 <<" "<< num3; } elseif (num2 > num3 && num3 > num1) { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num2 <<" "<< num3 <<" "<< num1; } elseif (num1 > num3 && num3 > num2) { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num1 <<" "<< num3 <<" "<< num2; } //when number is in the decreasing order else { //display the number in the decreasing order cout<<"The number in the decreasing order is "<< num3 <<" "<< num2 <<" "<< num1; } return 0; } Explanation: In the above program three integer type variable named num1, num2, and num3 is used to store the integer number entered by the user. Prompt the user to enter the three integer number. Store the user entered numbers in the integer variable named num1, num2, and num3. Using the IF ELSE statement display the number in the decreasing order. Sample Output:
