To understand this example, you should have the knowledge of the following C programming topics:
#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, freq);
return 0;
}
Output
Enter a string: This website is awesome. Enter a character to find its frequency: e Frequency of e = 4
In this program, the string entered by the user is stored in str.
Then, the user is asked to enter the character whose frequency is to be found. This is stored in variable ch.
Then, a for
loop is used to iterate over characters of the
string. In each iteration, if the character in the string is equal to the
ch, count is increased by 1.
Finally, the frequency stored in the count variable is printed.
