    Syntax error !

    Hi,
    This code is supposed to calculate the dot product of two 3-dimensional vectors.
    I get syntax error in line 29. (syntax error before ']' token)
    Code:
    #include<stdio.h>
    #include<stdbool.h>
    #include<stdlib.h>
    
    /* UTILITIES */
    
    #define MAX 3
    float dot_prod(float v1[], float v2[]);
    
    /* MAIN */
    
    int main()
    {
      int i;
      float v1[MAX],
        v2[MAX],
        result;
       
      printf("Enter the first vector\n");
      for (i=0; i<MAX ; i++){
        printf(":");
        scanf("%f",&v1[i]);
      }
      printf("Enter the second vector\n");
      for (i=0; i<MAX ; i++){
        printf(":");
        scanf("%f",&v2[i]);
      }
      result=dot_prod(v1[], v2[]);   /* Line 29 */
      
      printf("%f",result);
      
       return 0;
    }
    
    /* DEFINITION */
    
    float dot_prod(float v1[], float v2[]){
      int i;
      float  a,
             b,
           tot,
       total=0;
      for(i=0;i<MAX;i++){
        a=v1[i];
        b=v2[i];
        tot=a*b;
        total=total + tot;
      }
        return total;
      }

    Code:
    result=dot_prod(v1, v2);   /* Line 29 */
    Just enter the names if the variables you want to pass, nothing else.
