PYTHON Study Guide - For Loop, Modulo Operation

c plus plus is a popular programming language introduced by john strawstrom in the year 1979. It is general purpose case sensitive language and it is called pre-compiled language. It contains both features of high level and low level language. C plus plus supports procedural programming and functional programming as well. There are different types of data type that acts as a keyword which is responsible to define a variable. The syntax of strings contains a collection of characters surrounded by double quotes for example here string is the type str is the name of the string and coffee is the value that is assigned to the string. For loop for loop is the repetition control structure that allows us to repeat a block of code for a fixed number of times instead of repeating the same code again and again. Another type of loop is while loop while loop are used in c plus are group of statements that are designed to perform a specific task. functions in c and c plus allow us to write a code inside the function and then we can use that code every time when we need it by mocking the function.

We have to use if condition because we want to find the even elements and the odd elements and for that we have to include if condition so we 'll write if array of i mod 2 that is if an element on dividing by 2 gives 0 as a remainder then it will it is even element so we'll increment the even variable this which we have written 0 will increment over here okay so in this question we have used array for loop and if else so now let 's try some other example. We will print the elements from 1 to 20 using while loop and with the help of function so first of all we 'll start with intermittent and inside int main will simply call or invoke the function by writing the name of the function print function. In order to give some space between each element while printing we have used double quotes with the space between them. Get line c in is used to take the input of a string and s is the name of the string. Now we will print another message saying that you have entered now here we'll print the string so next line and then okay now we 'll do some operations like s dot pushback this will add an element at the end of the. string. There are some more examples on each of these topics we have covered.

program and see what happens so please enter your message so we get this message now. What we want to do is display this message for as long as the user remains in our program. So we use the while loop so we type while True which means while the condition is True. So In this case the condition is that our message variable is not empty and that 's why we put a comma after while because that 's what tells Python to keep looping while this condition is met okay now if you type exit out of our program right now you will get an error message because our while loop condition is not met Okay. So now let's add a counter to our program. So we can keep track of how many times our while loop condition has been met. So we add a variable called counter and set it to 1. Now if you run our program again and type exit out. of it, you will see that our while loop condition has been met four times. Now Let's add another counter and set it to 2 now. If you run our program again and type exit out of it. You will see that our while loop condition has been met six times now let's add another counter and set it to 3. Now If you run our program again and type exit out of it, you will see that our while loop condition has been met nine times now finally let's add another counter and set it to 4. Now. If you run our program again and type exit out of it. You will see that our while loop condition has been met 12 times. So this is how we can use the while loop in Python to write a value to the user. So next time I 'll show you how to read values from the user and how to write values to the user. THe passage discusses how an error occurred in a program. THe error was caused by attempting to subtract a string from an integer, which Python does not support. TO solve the problem, the author converted the string to an integer and solved the problem.. function is the string that we got from the input function now let's run the program so 10 and 20.1 and here 's the result In. This passage, the author explains how to solve a problem in Python where two numbers are being combined together as strings.. THe first number is read into a variable, and the second number is read into a second variable.. THe sum of the two numbers is then calculated using the float function, which converts both numbers to their. numeric representations. Finally, the sum of the two numbers is displayed on the terminal. One way to solve This problem would be to use the int function, which would convert both numbers to integers. However,. Since we're dealing with strings, we need to use the float function instead. Additionally,. Since we're not required to use the float function, we could have just called it at the time. We wanted to calculate the sum of the two numbers. IN conclusion,. This passage provides some insights into how to solve a problem in Python where two numbers are being combined together as strings.. The first step is to read in the first number into a variable, and the second step is to read in the second number.. The sum of the two numbers is then calculated using the float function, which converts both numbers to their numeric representations.. Finally, the sum of the two numbers is displayed on the terminal..
