Sum of Digits in a String Program plan: Include the required header files to the program. Declare function prototype which is used in the program. Define the “main()” function. Declare the required variables. Get the input C-string from the user and call the function “digit” with the input C-string. The “for” loop is used to convert the C-string to digit Call the function “digit” with an argument and store it in a variable. Sum all that values and store in a separate variable.

Define an array to hold an empty string value. Convert that string to integer using “atoi” function. If the input is not a digit, return 0. Finally return the result to the main function.

Question

A cylinder of diameter 10 cm rotates concentrically inside another hollow cylinder of inner diameter 10.1 cm. Both cylinders are 20 cm long and stand with their axis vertical. The annular space is filled with oil. If a torque of 100 kg cm is required to rotate the inner cylinder at 100 rpm, determine the viscosity of oil. Ans. μ= 29.82poise

Sum of Digits in a String

Program plan:

Include the required header files to the program.

Declare function prototype which is used in the program.

Define the “main()” function.

Declare the required variables.

Get the input C-string from the user and call the function “digit” with the input C-string.

The “for” loop is used to convert the C-string to digit

Call the function “digit” with an argument and store it in a variable.

Sum all that values and store in a separate variable.

Found the highest and lowest value of the C-string using “if” condition.

Print the result.

Define the “digit” function.

Declare the required variable.

Convert the character string to integer.

Define an array to hold an empty string value.

Convert that string to integer using “atoi” function.

If the input is not a digit, return 0.

Finally return the result to the main function.

Make the following game user friendly with GUI, with some simple graphics The following code works as this: The objective of the player is to escape from this labyrinth. The player starts at the bottom left corner of the labyrinth. He has to get to the top right corner of the labyrinth as fast he can, avoiding a meeting with the evil dragon. The player can move only in four directions: left, right, up or down. There are several escape paths in all labyrinths. The player’s character should be able to moved with the well known WASD keyboard buttons. If the dragon gets to a neighboring field of the player, then the player dies. Because it is dark in the labyrinth, the player can see only the neighboring fields at a distance of 3 units.
