Introduction Programmeringsteknik DT143G Lecture 5: Loops Pascal Rebreyend 18-11-2024 Pascal Rebreyend Programmeringsteknik DT143G  Introduction Today’s contents While loops Do-while loops For loops Nested loops Breaks in a loop Pascal Rebreyend Programmeringsteknik DT143G  Introduction Loops Another way to modify and control the flow of instructions Idea: To repeat some instructions for some number of times Some usages: Repeat asking the user if he/she is not entering a valid value Mathematical computations Looping on variables,... to find max,min,average,... going through a table, array (later) Pascal Rebreyend Programmeringsteknik DT143G  Introduction While loop while (criteria) statement; or while (criteria){ statement1; statement2;... } Pascal Rebreyend Programmeringsteknik DT143G  Introduction Flowchart: While loop Previous statement False criteria? True Statement (body) continue..
