Write a C program to print the words in a file starting with the given character.
#include <stdio.h>
#include <string.h>
#define MAX 256
int main() {
int ch;
FILE *fp;
char word[MAX], fname[MAX];
/* get the input file name from the user */
printf("Enter your input file name:");
fgets(fname, MAX, stdin);
fname[strlen(fname) - 1] = '\0';
/* get the input character from the user */
printf("Enter your input character:");
ch = getchar();
/* open the input file in read mode */
fp = fopen(fname, "r");
/* error handling */
if (!fp) {
printf("Unable to open the input file!!\n");
return 0;
}
/* print the words starting with input character */
while (!feof(fp)) {
strcpy(word, "\0");
fscanf(fp, "%s", word);
if (word[0] == ch) {
printf("%s\n", word);
}
}
#include <string.h>
#define MAX 256
int main() {
int ch;
FILE *fp;
char word[MAX], fname[MAX];
/* get the input file name from the user */
printf("Enter your input file name:");
fgets(fname, MAX, stdin);
fname[strlen(fname) - 1] = '\0';
/* get the input character from the user */
printf("Enter your input character:");
ch = getchar();
/* open the input file in read mode */
fp = fopen(fname, "r");
/* error handling */
if (!fp) {
printf("Unable to open the input file!!\n");
return 0;
}
/* print the words starting with input character */
while (!feof(fp)) {
strcpy(word, "\0");
fscanf(fp, "%s", word);
if (word[0] == ch) {
printf("%s\n", word);
}
}
/* close the opened file */
fclose(fp);
return 0;
}
