Question

Write a code that reads a line of text from standard in, and writes it to a file called "output.txt"

in C please

Answer 1

program logic:

• Define a character array of required size.
• Read a line from stdin, make sure that the delimiter is set to newline character, not spaces.
• Then, open the file output.txt in write mode.
• write the line to this file using fprintf()

program:

#include <stdio.h>

int main()
{
char line[1000];
FILE* f;
f = fopen("output.txt","w");
scanf("%[^\n]",line);
fprintf(f, "%s", line);
fclose(f);
return 0;
}

sample input:

Hello world!

output file:

Open output.txt ~/cc Save Hello World! Loadi... Plain Text Tab Width: 8 Ln 1, Col 13 INS m
