printf(“%s 缓冲区[k]”,缓冲区[k],k); 仅打印 > 缓冲区而不是 %s

Question

I'm making a puzzle game so I want to write word uppercase when user found that word. So I wrote this loop but it isn't working. Program isn't getting into IF statement. I've tried to print printf("%s Buffer[k]",buffer[k],k); in the second for (i) to find the problem but I didn't see words, program only printed " Buffer[0] \n Buffer[1] \n..........Buffer[9]".
But when I printed these printf("%s Buffer[k]",buffer[k],k); in first loop it printed correctly. How can I fix this?
and my second question is:
Why it isn't get into IF statement?

CODE 1:

for(int k=0; k<MAX_WORD_NUMBER; k++){
            for(int i=0; i<MAX_WORD_LENGTH; i++){
                printf("%s Buffer[k]",buffer[k],k);
                if(strcmp(buffer[k],word) == 0){                    
                    buffer[k][i] = word[i] - 32;
                }
                else{
                    break;
                }
            }
        }       

OUTPUT:

Buffer[0]
Buffer[1]
.
.
.
Buffer[8]
Buffer[9]

CODE 2:

for(int k=0; k<MAX_WORD_NUMBER; k++){
     printf("%s Buffer[k]",buffer[k],k);
        for(int i=0; i<MAX_WORD_LENGTH; i++){
            if(strcmp(buffer[k],word) == 0){                    
                buffer[k][i] = word[i] - 32;
            }
            else{
                break;
            }
        }
    }       

OUTPUT:

wall Buffer[0]
evasive Buffer[1]
. 
.
.
war Buffer[9]

[SOLVED]
I've changed MAX_WORD_LENGTH to strlen(word) and strncmp instead of strcmp
