Need ASAP help with a function (program)!!!

[Alenik1989]

I wrote this code, but I'm not able to test it because im getting 3 errors. So I'm not sure that this code will work properly or not!!!

the code in

#include <stdio.h>
#include <stdlib.h>
int rnd(char s1[],char s2[],char c[]);
int GetSt(char s1[],char s2[],char c[]);
void SearchAndPrint (char s1[], char s2[], char c[], int length);
 
int main ()
{
     char s1[41];
     char s2[21];
     char c[2];
    int answer,m;
    while(answer !='n')
    {
    m=rnd(s1,s2,c);
    if (m==-1)
    {
        printf("ERROOORRR\n");
        printf("wanna cont press enter or n to exit\n");
          answer=getchar();
         continue;
    }
    else
    {
         printf("wanna cont press enter or n to exit\n");
          answer=getchar();
    }
    return 0;
}
 
 
 
 
 
int rnd(char s1[],char s2[],char c[])
{
    int i,n;
     for(i=0;i<41;i++)
         s1[i]=rand() %26 + 'A';
         s1[i]='\0';
 
         n=GetSt(s1,s2,c);
             if(n==-1)
                 return -1;
             else 
                 return 1;
}
 
 
int GetSt(char s1[],char s2[],char c[])
{
    int n,i,length,m;
     printf("enter a char\n");
         c[0]=getchar();
         if((n=getchar())!='\n')
         {
             printf("ERROOORRR\n");
         while(n!='\n')
         {
             n=getchar();
         }
        return -1;
         }
         c[1]='\0';
 
         printf("enter char\n");
         i=0;
         while(i<21)
         {
             if( (m=getchar()) !='\n')
             {
                 if('A'<=m && m<='Z')
                 {
                 s2[i]=m;
                 i++;
                 }
                 else if ('a'<=m && m<='z')
                 {
                     m=m-32;
                     s2[i]=m;
                     i++;
                 }
                 else
                 {
                     while(m!='\n')
                 m=getchar();
                         break;
                 }
 
             }
             else
             {
                 s2[i]='\0';
                 break;
             }
         }
         length=i;
         if(i==21)
         {
             printf("error 2\n");
             while(m!='\n')
                 m=getchar();
             return -1;
         }
         else if(i<2)
         {
             printf("error 3\n");
             return -1;
         }
         else
         {
             SearchAndPrint(s1,s2,c,length);
             return 1;
         }
}
 
 
void SearchAndPrint (char s1[], char s2[], char c[],int length)
{
    int i,j;
    char cha;
 
             for (i=0;i<length;i++)
             {
                 cha=s2[i];
                 for(j=0;j<41;j++)
                 {
                     if(s2[j]==cha)
                     {
                         s2[j]=c[0];
                         continue;
                     }
                     else
                     {
                         continue;
                     }
                 }
             }
             puts(s1);
             puts(s2);
             puts(c);
}
 

And im getting 3 errors like:

:\Temp\lab213.c(36) : error C2143: syntax error : missing ';' before 'type'
I:\Temp\lab213.c(39) : error C2065: 'i' : undeclared identifier
I:\Temp\lab213.c(43) : error C2065: 'n' : undeclared identifier
 

Note: All the above errors are about the function
int rnd(char s1[],char s2[],char c[])
Please help!!!!!

You're missing a } to close main().

rand() returns a double. Use (char) to cast to char so it goes into your array.
