如何使用 c 编程计算 csv 文件中的行数和列数

Question

#include <stdio.h>
 
int main()
{
    FILE *fileptr;
    int count_lines = 0;
    char filechar[40], chr;
 
    printf("Enter file name: ");
    scanf("%s", filechar);
    fileptr = fopen(filechar, "r");
    chr = getc(fileptr);
    while (chr != EOF)
    {
        if (chr == 'n')
        {
            count_lines = count_lines + 1;
        }
            chr = getc(fileptr);
    }
    fclose(fileptr); //close file.
    printf("There are %d lines in %s  in a file\n", count_lines, filechar);
    return 0;
}

here i am able to count the no of row but i dont know how to count the no of col please help me out the main is i not am able to count no of comma in csv file so if i am able to count no of comma then it easy to know how much column in csv file

Answer 1

#include<stdio.h>
#include<conio.h>

int main(){

    FILE *fptr;
    int countline = 0, comma = 0;
    char file_char[40], chr;

    printf("Enter the file name");
    scanf("%s", file_char);

    fptr = fopen(file_char, "r");
    chr = getc(fptr);

    while(chr != EOF){
        if((chr == ",") && (countline == 0)){
            comma++;
        }
        if(chr == "\n"){
            countline++;
        }
        chr = getc(fptr);
    }
    fclose(fptr);
    printf("THERE %d line and %d rows", countline, comma + 1);
    return 0;
}

now i do the changes but still it show me problem
