Program in C
Here is the source code of the C Program to Find the second most frequent character in a given string.
Code:
#include<stdio.h>
#include<string.h>
main()
{
char str[30];
printf("Enter your String:");
scanf("%[^\n]",str);
int i,max=0,sec_max=0;
int arr[256]={0};
for(i=0;i<strlen(str);i++)
{
if(str[i]==' ')
continue;
arr[str[i]]++;
}
for (i = 0; i <256; i++) {
if (arr[i]>arr[max]) {
sec_max=max;
max = i;
}
else if(arr[i]>arr[sec_max] && arr[i]!=arr[max]){
sec_max=i;
}
}
printf("The Second Most occurring character in a string is %c",sec_max);
