Given a sentence and a character, count occurrence of the given character in the sentence. All characters in the sentence are lower case. code example

Example 1: find character from string c count

#include <stdio.h>
#include <string.h>
 
int main()
{
    char s[1000],c;  
    int i,count=0;
 
    printf("Enter  the string : ");
    gets(s);
    printf("Enter character to be searched: ");
    c=getchar();
    
    for(i=0;s[i];i++)  
    {
    	if(s[i]==c)
    	{
          count++;
		}
 	}
     
	printf("character '%c' occurs %d times \n ",c,count);
 
 	 
     
    return 0;
}

Example 2: c program to the count the number of times each character appears

#include <stdio.h>
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;
}
