Question

Write a program in C++ that will take an input array e.g.; alphabet[] ={'A', 'B', 'C', 'D', 'E', 'F', 'G'}. print out every other character of the alphabet i.e.; A, C, E, G

Answer 1

Code:

//including iostream libraby for input and output to console

#include<iostream>

//we have to specify a namespace in c++

using namespace std;

//execution starts at main

int main(){

//defining a array for data type character to store alphabets

char alphabet[]={'A','B','C','D','E','F','G'};

//we can use a for loop to iterate through array(for loop is a default functionality in c++ to execute some statements repeatedly)

//calculating the size of array

int array_size=sizeof(alphabet)/sizeof(char);

//int i=0 is a initial statement and

//this i<array_size will make sure statements inside the for loop will execute only till i is less than array size

//value of i will increment by 2 for each iteration

for(int i=0;i<array_size;i=i+2){

//cout is used to print alphabets to console

cout<<alphabet[i]<<",";

}

}

OUTPUT:

A,C,E,G,

Code with out comments:

#include<iostream>

using namespace std;

int main(){

char alphabet[]={'A','B','C','D','E','F','G'};

int array_size=sizeof(alphabet)/sizeof(char);

for(int i=0;i<array_size;i=i+2){

cout<<alphabet[i]<<",";

}

}
