int main(void)
    {
    
    
    char s[30]="fiordi";
    char *c;
    int cp,i,place;

    printf("Enter char: ");
    scanf("%s",&c);

    
    for(i=0; i<6; i  ){
   
     cp=strcmp(s[i],c);  
       if( cp == 0 ){
          place=i;
       }

strcmp compares strings, not characters. Without going into the details of why it doesn't work, you could just compare the characters directly:

   if(s[i] == c[0] ){
      place=i;
   }
