Count total occurrence of each character in a given file. code example
Example 1: How do you count characters in a string array in Java?
package practical5;
import java.util.Arrays;
public class Part1_9 {
public static void main(String[] args) {
// declaring and populating array
String quoteArray[] = { "\"Continuous", "effort", "not", "strength",
"nor", "intelligence", "is", "the", "key", "to", "unlocking",
"our", "potential.\"\n" };
// for loop to print full array
for (int counter = 0; counter < quoteArray.length; counter++) {
System.out.print(quoteArray[counter] + " ");
}// end of for loop
// Printing array using Enhanced for/ for each loop (Different way to
// print array)
for (String element : quoteArray) {
System.out.print(element + " ");
}// end of enhanced for
// line break
System.out.println();
// printing number of words in array
System.out.println("Number of words in array: " + quoteArray.length);
**// printing total number of letters in array**
for (int counter = 0; counter < quoteArray.length; counter++) {
String letters = new String(quoteArray[counter]);
}
// printing the smallest word
// printing the biggest word
}// end of main
}// end of class
Example 2: c program to the count the number of times each character appears
int main() {
char str[1000], ch;
int count = 0;
printf("Enter a string: ");
fgets(str, sizeof(str), stdin);
printf("Enter a character to find its frequency: ");
scanf("%c", &ch);
for (int i = 0; str[i] != '\0'; ++i) {
if (ch == str[i])
++count;
}
printf("Frequency of %c = %d", ch, count);
return 0;
}
