How I can fix this array

Good morning, I was trying to fill a dynamic vector but when I print the input data i get something like this:

input: 1,5,3,4,2
output: 0,1,5,3,4

Could somebody help me I can't fix it I've been trying a lot and can't get it. I'll apreciatte so much (sorry for the english)

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

#define MAX_STR 10

int vecto();

char seguir[MAX_STRLEN];
int var;

float* vector; 
char* bv;

int vecto(){
int cont=0,ch;
char v[MAX_STR];
printf ("¿number of elements to order?: ");
scanf("%d",&var);
vector = (float*)malloc(var*sizeof(float));
while((ch = fgetc(stdin)) != EOF && ch != '\n' ){};
printf("input number press f for finish \n");
    do{
    fgets(v,sizeof(v),stdin);
    if((strcmp(v,"f")!=0)){
        cont++;
        vector[cont]=strtod(v,&bv);
    }
    }while(!((cont==var) || (strcmp(v,"f")==0)));
printf("\n");
return 0;
}
