C program to find the minimum occurring characters in a string; Through this tutorial, we will learn how to find the minimum or lowest occurring characters in a string using the for loop and function in c programs.
Programs to Find Minimum Occurring Character in a string in C
- C Program to Find Minimum Occurring Character in a string using For Loop
- C Program to Find Minimum Occurring Character in a string using Function
C Program to Find Minimum Occurring Character in a string using For Loop
#include <stdio.h>
#include <string.h>
int main()
{
char str[100], result;
int i, len;
int min = 0;
int freq[256] = {0};
printf("\n Please Enter any String : ");
gets(str);
len = strlen(str);
for(i = 0; i < len; i++)
{
freq[str[i]]++;
}
for(i = 0; i < 256; i++)
{
if(freq[i] != 0)
{
if(freq[min] == 0 || freq[i] < freq[min])
{
min = i;
}
}
}
printf("\n Character '%c' appears Minimum of %d Times in a Given String : %s ", min, freq[min], str);
return 0;
}
The Output of the above c program; as follows:
Please Enter any String : hello c programmer Character 'a' appears Minimum of 1 Times in a Given String : hello c programmer
