Write a single C statement to accomplish each of the following

Write a single C statement to accomplish each of the following:

a) Define the variables c, this Variable, q76354 and number to be of type int.

b) Prompt the user to enter an integer. End your prompting message with a colon (:) followed by a space and leave the cursor positioned after the space.

c) Read an integer from the keyboard and store the value entered in integer variable a.

d) If number is not equal to 7, print “The variable number is not equal to 7.”

e) Print the message “This is a C program.” on one line.

f) Print the message “This is a C program.” on two lines so that the first line ends with C.

g) Print the message “This is a C program.” with each word on a separate line.

h) Print the message “This is a C program.” with the words separated by tabs.

The Correct Answer and Explanation is :

Here are the C statements for each part of the task:

a) Define the variables c, thisVariable, q76354, and number to be of type int.

int c, thisVariable, q76354, number;

b) Prompt the user to enter an integer. End your prompting message with a colon (:) followed by a space and leave the cursor positioned after the space.

printf("Enter an integer: ");

c) Read an integer from the keyboard and store the value entered in integer variable a.

scanf("%d", &a);

d) If number is not equal to 7, print “The variable number is not equal to 7.”

if (number != 7) {
    printf("The variable number is not equal to 7.\n");
}

e) Print the message “This is a C program.” on one line.

printf("This is a C program.\n");

f) Print the message “This is a C program.” on two lines so that the first line ends with C.

printf("This is a C\nprogram.\n");

g) Print the message “This is a C program.” with each word on a separate line.

printf("This\nis\na\nC\nprogram.\n");

h) Print the message “This is a C program.” with the words separated by tabs.

printf("This\tis\ta\tC\tprogram.\n");

Explanation:

1. a) Declaring Variables: The int keyword is used to define variables of integer type. Each variable is separated by a comma.
2. b) Prompting the User: The printf function is used to print messages to the console. The : and the space are explicitly included in the message string.
3. c) Reading Input: The scanf function is used to read input from the user. %d is the format specifier for integers, and &a is the address of the variable a where the input is stored.
4. d) Conditional Check: An if statement checks if number is not equal to 7. If true, it prints a message using printf. The != operator checks inequality.
5. e) Printing on One Line: The printf function prints the string and ends with \n to indicate a newline, ensuring the output appears on a single line.
6. f) Printing on Two Lines: By placing \n within the string at the appropriate location, the string is split between two lines.
7. g) Printing Each Word on a Separate Line: Each word is printed followed by \n to place it on a new line.
8. h) Printing with Tabs: The \t escape sequence inserts a tab character between words, resulting in tab-separated output.

These statements showcase how to handle input, output, and conditional logic in C programming. By using escape sequences like \n (newline) and \t (tab), you can control the formatting of the output. Each of these tasks helps in learning how to interact with the user and manipulate text output in C.
