Finding Mode Value In Array
#include <stdio.h>
int mode(int arr[], int size); // function prototype
int main(void){
// in following simple program we will create a function which will accept an array as an input
// Furthermore that function will return mode value from the array elements
// mode value is the most repeated value of the elements
int arrayName[10] = {2,4,4,4,1,2,3,4,2,3}; // defined an array with 10 elements
//output each element of array
printf("Original values of the array\n\n");
printf("Array index\t\t\tValue\n");
for(int j=0; j<10; j++){
printf("%11d\t\t\t%4d\n", j, arrayName[j]);
}
int a = mode(arrayName, 10); // function call
printf("\n\nMode Value is: %d", a);
return 0;
}
//function definition
int mode(int arr[], int size){
int freq[size] = {0};
for(int i=0; i<size; i++){
freq[arr[i]]++;
}
printf("\nFrequency of each array element\n\n");
printf("Array index\t\t\tValue\n");
for(int j=0; j<10; j++){
printf("%11d\t\t\t%4d\n", j, freq[j]);
}
int largest = 0;
for (int j=0; j<size; j++){
if(freq[j]>freq[largest]){
largest = j;
}
}
printf("\nFrequency of each array element (graphical representation)\n\n");
printf("Array index\t\t\tFrequency\n");
for(int i=0; i<size; i++){
printf("%11d\t\t\t",i);
for(int j=0; j<freq[i]; j++){
printf("*");
}
printf("\n");
}
return largest;
}OUTPUT:-
0 0
1 1
2 3
3 2
4 4
5 0
6 0
7 0
8 0
9 0
Frequency of each array element (graphical representation)
