How Can I replace this type "int" by"String" in c programming? -

this question has answer here:

• how check if value matches string 3 answers

i'm using dev c++ . silly program ask correct key show text. program working type "int" (just numbers):

    #include <stdio.h>     #include<conio.h>      main()     {         int key;          printf("this program show mensage if correct key \n");         printf("write key:\n");         scanf("%i",&key);             if(key==1234)             {                 printf("welcome stackoverflow \n");             }             else             {                 printf("you keep going slept \n");             }             getch();              return 0;      } 

but how can replace strings example: sesame, house , on.

i've tried matrix:

char key[]; 

however error.

sincerily nin.

update:

i new program :

#include <stdio.h> #include<conio.h>  main() {     char key[7]; /*replace int char*/      printf("this program show mensage if correct key \n");     printf("write key:\n");     scanf("%c",&key);         if(key=="sesame") /*numbers string*/         {             printf("welcome stackoverflow \n");         }         else         {             printf("you keep going slept \n");         }         getch();          return 0;  } 

however though fix correct key ("sesame") "you keep going slept"

problem 1:

scanf("%c",&key); 

is not right. read 1 character. need use

scanf("%6s", key); 

problem 2:

    if(key=="sesame")  

is not proper way compare 2 strings. compare 2 pointers , evaluate false. need use:

    if( strcmp(key, "sesame") == 0 )
