If the number is 100 or less than 100 then you should print out the message: The number is not bigger than 100. Make certain that your code looks good. No ragged indents. 62) Write the section of code required to print the sum of the first n integers (starting with 1)where n is a positive number entered from the keyboard by the user.

No ragged indents. 62) Write the section of code required to print the sum of the first n integers (starting with l)where n is a positive number entered from the keyboard by the user. You may assume you have all required include directives and that the user will not enter a negative number. 63) Canning Problem 2: Write a C program that prints out the value 6. I want you to use the %d format code. Your textbook explains about format codes. 64) Canning Problem l: Write a C program that prints out the message Hello World. 65) Canning Problem 4: Write a C program that reads an integer value from the keyboard via the scanffunction and then prints it back onto the screen.

68) Write a complete program that will ask the user for two values of type double and then print the average on the screen with a message that says whether the average is a positive number or a negative number. 69) Canning problem 5: Write a C program that reads two integer values from the keyboard via the scanf function, then adds them together, stores the result into a variable called sum, and then prints out the value of the variable sum. I want you to use a single call to scanf. Do not use two separate calls to scanf. 8 68) Write a complete program that will ask the user for two values of type double and then print the average on the screen with a message that says whether the average is a positive number or a negative number. 69) Canning problem 5: Write a C program that reads two integer values from the keyboard via the scan/ function, then adds them together, stores the result into a variable called sum, and then prints out the value of the variable sum.
