C program to count a letter repeated in a sentence.
Problem
Write a program to count a letter, which is entered by the user at console. How many times that letter is repeated in a sentence need to be printed on screen by using strlen() function.
Solution
The logics we used to count a letter are as follows −
- Asking the user to enter a sentence at runtime.
printf("Enter a sentence
");
gets(str);- Asking the user to enter a letter at runtime.
printf("Enter a character to check how many times it is repeating
");
scanf("%c",&c);- The logic to count the letter in a sentence is as follows −
for(i=0;i<strlen(str);i++){
if(str[i]==c){
count++;
}
}- Finally print the count
Example
Following is the C program to count a letter that is repeated for number of times in a sentence −
#include<stdio.h>
#include<string.h>
main(){
int i,count=0;
char c,str[100];
printf("Enter a sentence
");
gets(str);
printf("Enter a character to check how many times it is repeating
");
scanf("%c",&c);
for(i=0;i<strlen(str);i++){
if(str[i]==c){
count++;
}
}
printf("Letter %c repeated %d times
",c,count);
}Output
When the above program is executed, it produces the following output −
Enter a sentence Here are the C Programming question and answers Enter a character to check how many times it is repeating n Letter n repeated 4 times
