Declare an integer variable named degreesCelsius. 2. Declare two integer variables named profitStartOfQuarter and cashFlowEndOfYear. 3. Write a single statement that will print the message “first is ” followed by the value of first, and then a space, followed by “second = “, followed by the value of second, Print everything on one line and go to a new line after printing. Assume that first has already been declared as a double and that second has been declared as an int. Assume also that the variables have already been given values. 4. Given an integer variable i and a floating-point variable f, that have already been given values, write a statement that writes both of their values to standard output in the following format: i=value-of-i f=value-of-f Thus, if i’s value were 25 and f’s value were 12.34, the output would be: i=25 f=12.34 But you don’t know what i’s value and f’s value are. They might be 187 and 24.06. If that’s what their values are, the output from your statement should be: i=187 f=24.06 On the other hand, they might be 19 and 2.001. If that’s what their values are, the output from your statement should be: i=19 f=2.001 Remember: you are GIVEN i and f– that means they are already declared and they already have values! Don’t change their values by assigning or initializing them! Just print them out the way we have shown above. Just write one statement to produce the output. Remember: in your output you must be displaying both the name of the variable (like i) and its value.
The Correct Answer and Explanation is :
Let’s address each of your requirements step by step:
1. Declare an integer variable named degreesCelsius:
In C, you can declare an integer variable as follows:
int degreesCelsius;This statement declares a variable degreesCelsius of type int, which can store integer values.
2. Declare two integer variables named profitStartOfQuarter and cashFlowEndOfYear:
Similarly, to declare two integer variables, you can write:
int profitStartOfQuarter, cashFlowEndOfYear;This declares two integer variables: profitStartOfQuarter and cashFlowEndOfYear.
3. Write a single statement that prints the message “first is ” followed by the value of first, a space, followed by “second = “, and then the value of second, all on one line, and then moves to a new line:
Assuming first is a double and second is an int, and both have been assigned values, you can use the printf function with appropriate format specifiers:
printf("first is %f second = %d\n", first, second);In this statement:
%fis the format specifier for adoublevalue.%dis the format specifier for anintvalue.\nis the newline character, which moves the cursor to the next line after printing.
This will output the values of first and second in the specified format.
4. Given an integer variable i and a floating-point variable f, write a statement that prints both of their values to standard output in the format: i=value-of-i f=value-of-f:
Assuming i is an int and f is a float, and both have been assigned values, you can use:
printf("i=%d f=%f\n", i, f);In this statement:
%dis the format specifier for anintvalue.%fis the format specifier for afloatvalue.\nis the newline character, which moves the cursor to the next line after printing.
This will output the values of i and f in the specified format.
Explanation:
In C, the printf function is used to print formatted output to the standard output (usually the console). The function takes a format string followed by a list of variables. The format string can contain text and format specifiers, which are placeholders for the variables.
Format specifiers start with a percent sign % and are followed by a character that indicates the type of the variable. Common format specifiers include:
%dforint%fforfloat%lffordouble%cforchar%sforstring
The \n character is used to insert a newline, moving the cursor to the next line after printing.
By using these format specifiers, you can control the output format and ensure that the variables are displayed correctly.
For more information on format specifiers and the printf function, you can refer to the GeeksforGeeks article on printf in C.
