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
[CODE=c]
#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("ERROOOR RR\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("ERROOOR RR\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);
}
[/CODE]
And im getting 3 errors like:
[CODE=txt]
:\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
[/CODE]
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.
