FREQUENCY
Frequency of a character in a given string implies no of occurences of that particular character in the given string.
For example:
String: Techcpp
Character: c
Frequency: 2
STEPS
1. Initialize count with 0.
2. Input an string and the character whose frequency is to be calculated within the entered string.
3. Initialize index variable i with 0
4. Increment the count if the condition 'ch equals to a[i]' is satisfied.
5. Increment i untill a[i]!='\0'.
PROGRAM
//Program to calculate the frequency of a character
# include <iostream>
using namespace std;
int main()
{
char a[20],ch;
int i,j,count=0;
cout<<"ENTER THE STRING:\n";
cin.getline(a,20);
cout<<"ENTER THE CHARACTER WHOSE FREQUENCY IS TO BE CALCULATED:\n";
cin>>ch;
for(i=0;a[i]!='\0';i++)
{
if(ch==a[i])
count++;
}
cout<<count;
return 0;
}
