c - Scanning double number in a matrix -


i scan matrix text file seems code wrote works integer not float.

#include <stdlib.h> #include <stdio.h> #define max 10000  int main(void) {   file *fp;   int i, j;   char s[max], ch;    if ((fp = fopen("3.txt", "r")) == null) {     printf("can not open file!\n");     exit(1);   }   int row = 0;   while (fgets(s, max, fp) != null) //count line     row++;    rewind(fp); //    int col = 0; //count col   while (ch != '\n') //(ch=fgetc(fp))!='\n'&&(ch=fgetc(fp))!='\r'   {     if (ch == ' ') col++;     ch = fgetc(fp);   }   col++; //    double** jz = malloc(row * sizeof(double*)); //allocate spaces   (i = 0; < row; i++)     jz[i] = malloc(col * sizeof(double));    rewind(fp);    (i = 0; < row; i++) //read in data     (j = 0; j < col; j++) {       if (!fscanf(fp, "%lf", &jz[i][j])) {         break;       }     }    (i = 0; < row; i++) //print matrix     (j = 0; j < col; j++) {       printf("%lf\t", jz[i][j]);       if (j + 1 == col) printf("\n");     }   fclose(fp); } 

for example, 1*3 matrix 56.154 59.365 98.3333 appear 0.0000

i know did wrong.
