The Program in C that will read a line of text and display number of words and number of characters is given below:
#include <stdio.h>
#include <string.h>
int main() {
char input[1000];
printf("Enter a line of text: ");
fgets(input, sizeof(input), stdin);
input[strcspn(input, "\n")] = 0; // remove newline char
int words = 1, characters = 0;
int i = 0;
while (input[i] != '\0') {
characters++;
if (input[i] == ' ') {
words++;
}
i++;
}
printf("Number of words: %d\n", words);
printf("Number of characters: %d\n", characters);
return 0;
}
Output:
Enter a line of text: codeauri is dope bros sis ,isnt it?
Number of words: 7
Number of characters: 35
Pro-Tips💡
This program uses the fgets() function to read a line of text from the keyboard, and stores it in the input variable.
It then removes the newline character that is appended to the input by fgets by replacing it with a null terminator.
It initializes two variables, words and characters to 1 and 0 respectively, and uses a while loop to iterate through each character in the input string.
If the current character is a space, it increases the value of the words variable, and for each character it increases the value of the characters variable.
Finally it prints the number of words and characters respectively, which is stored in words and characters variables.
