write to file c code example
Example 1: read files in c
#include<stdio.h>
int main(){
FILE *in=fopen("name_of_file.txt","r");
char c;
while((c=fgetc(in))!=EOF)
putchar(c);
fclose(in);
return 0;
}
Example 2: write in file in c
#include<stdio.h>
int main(){
FILE *out=fopen("name_of_file.txt","w");
fputs("Hello File",out);
fclose(out);
return 0;
}
Example 3: c write to file
#include <stdio.h>
#include <stdlib.h>
int main() {
char sentence[1000];
FILE *fptr;
fptr = fopen("program.txt", "w");
if (fptr == NULL) {
printf("Error!");
exit(1);
}
printf("Enter a sentence:\n");
fgets(sentence, sizeof(sentence), stdin);
fprintf(fptr, "%s", sentence);
fclose(fptr);
return 0;
}
Example 4: c program to read and write to a file
#include <stdio.h>
int main() {
FILE *fp;
char ch;
fp= fopen ('example.txt', 'r');
while( (ch = getc(fp)) != EOF) {
printf('%ch', ch);
}
fclose(fp);
return 0;
}
Example 5: file in C
FILE=*fp;
fp=fopen("one.txt", "w");
fclose(fp);
Example 6: write to file in c programming
[...]
printf("Enter name: \n");
if (fgets(name, sizeof name, stdin)) {
fputs(name,fileptr);
fclose(fileptr);
printf("File write was successful\n");
} else {
printf("Read error.\n");
}
