Okay, I know there is a prior article about this, but I used { } with my if statements, and it's still not working... is it because I have multiple if statements consecutively after another?

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

    int i, n,t, s[51],p=1,a,b,c; 
int main() {
            srand(1);
        for(i=0;i<=51;i++) {
            if (p>13)           {
                p=1;            }  
                s[i] = p;
                p++;
                           }
printf("\n");
  for(i=0;i<52;i++) {
  a = n;  
  n = rand()%52;
    if (s[n]<0 || s[a]<0)  {
                --i;            }
    else    {
        if ((s[n]=1)) {  
            b=11;
            printf("A + "); }
        else if (s[n] == 11); {  
            b=s[n];
            printf("J + "); }
        else if (s[n] == 12); {   
            b=s[n];
            printf("Q + "); }
        else if (s[n] == 13); {       
            b=s[n];
            printf("K + "); }
        else {  
            b=s[n];
            printf("%i + ",b); }

        if ((s[a]=1)) {  
            c=11;
            printf("A = "); }
        else if (s[a] == 11); {  
            c=s[a];
            printf("J = "); }
        else if (s[a] == 12); {   
            c=s[a];
            printf("Q = "); }
        else if (s[a] == 13); {    
            c=s[a];
            printf("K = "); }
        else {  
            c=s[a];
            printf("%i = ",c); }

        if((b+c=21)){
            printf("%i blackjack!\n",b+c);
                    s[n]=-1;
                    s[a]=-1;}
        else{
            printf("%i\n",b+c);
                    s[n]=-1;
                    s[a]=-1;                          
                    }
            }
                    }
 return 0;  }

these are the errors I'm coming up with:
p2.c:29: error: 'else' without a previous 'if'
p2.c:32: error: 'else' without a previous 'if'
p2.c:35: error: 'else' without a previous 'if'
p2.c:44: error: 'else' without a previous 'if'
p2.c:47: error: 'else' without a previous 'if'
p2.c:50: error: 'else' without a previous 'if'
p2.c:53: error: lvalue required as left operand of assignment

No, it's because you have formatting that hides your problem. See this for proper formatting suggestions.

Anyway, on your problem is that for every else if statements, you added a semicolon after the condition. You are not supposed to do that. Additionally, you're missing another equal sign at line 53.
