c Remove the spaces in txt

Answer 1

If you wanted to remove the spaces in the txt-file in C language, you could do it by reading the contents of the file, processing the spaces in the string, and then writing the processed content into a new file. The following was a basic idea:

1. ** Open a file **: Use the `fopen` function to open the txt-file in a suitable mode (such as the read mode `r"`).
2. ** Read file contents **: You can use the `fgets` function to read the file contents line by line into a character array (buffer).
3. ** Dealing with spaces in the string **: Traverse the string you read. For spaces, you can choose not to copy them or use other logical processing to remove them. For example, you can create a new character array and copy the non-space characters into the new array.
4. ** Write to a new file **: Use the `fopen` function to open a new TMT file in write mode (such as `"w"`), and then write the processed string into the new file using `fputs` or `fprint` functions.
5. ** Close the file **: After processing, use the `fclose` function to close the open file.

The following is a simple sample code fragment (only for illustration, does not include complete error handling, etc.):

```c
#include
#include

void removeSpacesFromFile() {
FILE *inputFile = fopen("input.txt", "r");
FILE *outputFile = fopen("output.txt", "w");
char buffer[1024];

if (inputFile!= NULL) {
while (fgets(buffer, sizeof(buffer), inputFile)!= NULL) {
int len = strlen(buffer);
int j = 0;
char newBuffer[1024];
for (int i = 0; i < len; i++) {
if (buffer[i]!= '') {
newBuffer[j] = buffer[i];
j++;
}
}
newBuffer[j] = '\0';
fputs(newBuffer, outputFile);
}
fclose(inputFile);
fclose(outputFile);
}
}

int main() {
removeSpacesFromFile();
return 0;
}

```

This code reads the contents of the file `input.txt', strips out the spaces, and writes the result to the file` output.txt'.
