Type the program's output 1-3 while i < 15: J = 5 while j <- 9: i- print (f' {i} {j}') J = j + 4 i + 13
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
1) Python code snippet in program does below steps
- The first while loop starts with i = 3, and continues until i < 15 (that is, i = 15 is not included in the loop).
- The while loop body contains another while loop that starts with j = 5, and continues until j <= 9 (that is, j = 9 is included in the loop).
- On each iteration of the inner while loop, the value of i is combined with the value of j to produce an output string, which is printed using print().
- The inner while loop runs twice, because j starts at 5 and is increased by 4 on each iteration, so j becomes 9 on the first iteration, and the loop still continues.
- On third iteration it breaks because j becomes 13 more than 9
- The outer while loop runs only once, then increments i by 13, making it equal to 16, which is greater than or equal to 15, so the loop terminates.
- The while loop body contains another while loop that starts with j = 5, and continues until j <= 9 (that is, j = 9 is included in the loop).
- Therefore, the final output is
- 35, which is the result of combining i = 3 and j = 5.
- 39, which is the result of combining i = 3 and j = 9.
2) Output of program is
35
39
