While do-while for

Repetition: Conditional - while loop

General format while ( check condition ) { executable1; executable2; change variable in conditional statement } Must make a change in conditional variable within the loop! Compile sam3.c and run.

While do-while for

Repetition: For a fixed number of times - for loop

General format for ( x = 0; x < maxValue; x++) { executable1; executable2; } Should NOT make a change in conditional variable! Compile sample6.c and run.

Practice problem

(^1) Write a program that will find the smallest, largest, and average values in a collection of N numbers. The number N will be given to the program by the user. Also compute and display the range of values in the data collection (the minimum and maximum numbers entered), and the standard deviation of the data collection. To compute the standard deviation, accumulate the sum of the squares of the data values (sum squares) in the main loop. After loop exit, use the formula

standarddeviation =

sum squares N − average^2
