    1 hard to read code in the txt file, try posting it on the post with the code button....
    2 your code, IF you even wrote it, is a complete mess!
    3 the error on 31 is the least of your probs with this code

    Here's what I see in Notepad, after a bit of editing:
    Code:
    #include<stdio.h>
    #include<conio.h>
    
    void display(int z);
    void display2(int z);
    
    int main(void)
    {
         int a,b,c,d;
         int x[16] = {0,10,20,25,30,40,50,60,70,75,80,90,100,100,100,100};
    
         printf("Enter the Val of A,B,C,D\n");
         scanf("%d,%d,%d,%d",&a,&b,&c,&d);
         printf("Val of a,b,c,d,%d,%d,%d,%d",a,b,c,d);
    
    /* your main function should call the other functions, but they should not be included inside main(), so: */
    
        display(z);
        display2(z);
    
        printf("Press enter to continue, when ready\n");
        getchar();
        return 0;
    } //end of main
    
    void display(int z);
    {
       int index = a*8 + b*4 + c*2 + d;
       printf("%d, %d, %d, %d is %d %%", a, b, c, d, x[index]);
       getch();
    }
    void display2(int z)  //make it display2. You can't have two functions with the same name and parameters
    {
         int a,b,c,d;
         int x[16] = {0,10,20,25,30,40,50,60,70,75,80,90,100,100,100,100};

    I just moved the other functions outside main() and gave one of them a different name to differentiate it from the other one. Didn't mean to imply it was OK.

    I had to leave.

    Here's an error free version, but it can't deliver good results.

    Code:
    #include<stdio.h>
    #include<conio.h>
    
    void display(int x[16],int a,int b,int c,int d);
    void display2(int x[16],int a,int b,int c,int d,int z);
    
    int main(void)
    {
         int a,b,c,d,z=0;
         int x[16] = {0,10,20,25,30,40,50,60,70,75,80,90,100,100,100,100};
    
         printf("Enter the Val of A,B,C,D\n");
         scanf("%d,%d,%d,%d",&a,&b,&c,&d);
         printf("Val of a,b,c,d,%d,%d,%d,%d",a,b,c,d);
    
    /* your main function should call the other functions, but they should not be included inside main(), so: */
    
        display(x,a,b,c,d);
        display2(x,a,b,c,d,z);
    
        printf("Press enter to continue, when ready\n");
        getchar();
        return 0;
    } //end of main
    
    void display(int x[16],int a,int b,int c,int d)
    {
       int index = a*8 + b*4 + c*2 + d;
       printf("%d, %d, %d, %d is %d %%", a, b, c, d, x[index]);
       getchar();
    }
    //make it display2. You can't have two functions with the same name and parameters
    void display2(int x[16],int a,int b,int c,int d,int z)  
    {
         //int a,b,c,d;
         //int x[16] = {0,10,20,25,30,40,50,60,70,75,80,90,100,100,100,100};
    
        if(a==0 && b==0 && c==0 && d==0)

           printf("%d, %d, %d, %d is %d %%", a,b,c,d, x[2]);//0010=02
