使用C将两个文件的内容合并到第三个文件中
这是一个ac程序，用于将两个文件的内容合并到第三个文件中。
例如。
输入值
java.txt is having initial content “Java是一种编程语言。” kotlin.txt is having initial content “ kotlin是一种编程语言。” ttpoint.txt is having initial content as blank
输出结果
files are merged ttpoint.txt will have final content as “Java是一种编程语言。 kotlin是一种编程语言。”
算法
Begin
Declare a[] array to the character datatype.
Initialize a[] = "Java是一种编程语言。".
Declare i of the integer datatype.
Initialize i =0.
Declare f1 as a pointer to the FILE type.
Open a file “java.txt” to perform write operation using f1 pointer.
while (a[i] != '\0')
call fputc(a[i], f1) to put all data of a[] into f1 file object i++
Close the f1 file pointer.
Declare a[] array to the character datatype.
Initialize b[] = " kotlin是一种编程语言。".
Declare i of the integer datatype.
Initialize j =0.
Declare f2 as a pointer to the FILE type.
Open a file “kotlin.txt” to perform write operation using f2 pointer.
while (b[j] != '\0')
call fputc(b[j], f1) to put all data of b[] into f2 file object j++
Close the f2 file pointer.
Open a file “java.txt” to perform read operation using f1 pointer.
Open a file “ttpoint.txt” to perform write operation using f2 pointer.
Declare f3 as a pointer to the FILE datatype.
Open a file “ttpoint.txt” to perform write operation using f3 pointer.
Declare a variable “c” to the character datatype.
if (f1 == NULL || f2 == NULL || f3 == NULL) then
print “couldn’t open the file.”
Exit.
While ((c = fgetc(f1)) != EOF) do
Put all data of “c” variable into f3 file pointer using fputc() function.
while ((c = fgetc(f2)) != EOF) do
Put all data of “c” variable into f3 file pointer using fputc() function.
Call fclose(f3) function to close the file pointer.
Open the file ttpoint.txt using f3 file pointer.
Print “Merged java.txt and python.txt into ttpoint.txt”
while (!feof(f3))
Call putchar(fgetc(f3)) function to print the content of f3 file pointer.
Close the f1 file pointer.
Close the f2 file pointer.
Close the f3 file pointer.
End.示例
#include <stdio.h>
#include <stdlib.h>
int main() {
char a[] = "Java是一种编程语言。";
int i=0;
FILE *f1; // Open two files to be merged
f1 = fopen("java.txt", "w");
while (a[i] != '\0') {
fputc(a[i], f1);
i++;
}
fclose(f1);
char b[] = "kotlin是一种编程语言。";
int j =0;
FILE *f2;
f2 = fopen("kotlin.txt", "w");
while (b[j] != '\0') {
fputc(b[j], f2);
j++;
}
fclose(f2);
f1 = fopen("java.txt", "r");
f2 = fopen("kotlin.txt", "r");
FILE *f3 = fopen("ttpoint.txt", "w"); // Open file to store the result
char c;
if (f1 == NULL || f2 == NULL || f3 == NULL) {
puts("Could not open files");
exit(0);
}
while ((c = fgetc(f1)) != EOF) // Copy contents of first file to ttpoint.txt
fputc(c, f3);
while ((c = fgetc(f2)) != EOF) // Copy contents of second file to ttpoint.txt
fputc(c, f3);
fclose(f3);
f3 = fopen("ttpoint.txt", "r");
printf("Merged java.txt and kotlin.txt into ttpoint.txt\n");
while (!feof(f3))
putchar(fgetc(f3));
fclose(f1); //closing the file pointer.
fclose(f2);
fclose(f3);
return 0;
}输出结果
Merged java.txt and kotlin.txt into ttpoint.txt Java是一种编程语言。kotlin是一种编程语言。
