How to store the words of a sentence into a 2-D array using C programming.

You need to initialize the arr_word array with a null terminator first because an uninitialized array has the potential to store garbage values.

And also, you need to added an additional condition to break the loop when it encounters a null terminator in the sentence ("line" array). This prevents the loop from storing a non-existing character, which could result in the output of a garbage value.

#include <stdio.h>
#include <string.h>

int main()
{
    char line[1000];
    scanf("%[^\n]%*c", line);
    int l=strlen(line),i,count=0;
    for(i=0;i<l;i++){
        if(line[i]==' '){
            count+=1;
        }
    }
    
   
    
    char arr_word[count+1][26];
    int j,ind=0;
    
/* intialize arr_word array */
    
     for(i=0; i <count+1; i++){
        for(j = 0; j <26; j++){
        arr_word[i][j] = '\0';
        }
    }
    for(i=0;i<count+1;i++){
        for(j=0;j<26;j++){
            if(line[ind]==' ' || line[ind]=='\0'){
                ind++;
                break;
            }
            arr_word[i][j]=line[ind];
            ind++;
        }
    }
    
    for(i=0; i <count+1; i++){
        for(j = 0; j <26; j++){
            printf("%c", arr_word[i][j]);
        }
        
        printf("\n");
    }
    return 0;
}
