Control Structures

Control structures: sequential, selection, iteration and encapsulation.

A sequential structure is one in which instructions are executed in sequence. For example,

<source lang="cpp"># include<stdio.h> main() {

   int i=0, j =1;
   printf("A");
   i = i + 1;
   printf("B");
   j = j + 1;
   printf("C");

}</source>

Selection structure

The sequence of the instruction is determined by the condition.

The statements in this category are if and switch.

<source lang="cpp"># include<stdio.h> main(){

   int i=0, j =1;
  
   if (i > j){
       i = i + 1;
       printf("a");
   }
   else{
       printf("b");
       j = j +1;
   }

}</source>
