Program for sorting of string in c language

#include<stdio.h>

int main(){

  int i,j,n;

  char str[20][20],temp[20];

  puts("Enter the no. of string to be sorted");

  scanf("%d",&n);

  for(i=0;i<=n;i++)

      gets(str[i]);

  for(i=0;i<=n;i++)

      for(j=i+1;j<=n;j++){

           if(strcmp(str[i],str[j])>0){

               strcpy(temp,str[i]);

              strcpy(str[i],str[j]);

              strcpy(str[j],temp);

           }

      }

  printf("The sorted string\n");

  for(i=0;i<=n;i++)

      puts(str[i]);

  return 0;

}

String concatenation in c without using string functions

#include<stdio.h>

void stringConcat(char[],char[]);

int main(){

    char str1[100],str2[100];

    int compare;

    printf("Enter first string: ");

    scanf("%s",str1);

    printf("Enter second string: ");

    scanf("%s",str2);

    stringConcat(str1,str2);

    printf("String after concatenation: %s",str1);

    return 0;

}

void stringConcat(char str1[],char str2[]){

    int i=0,j=0;

   

   

    while(str1[i]!='\0'){

         i++;

    }

    while(str2[j]!='\0'){

         str1[i] = str2[j];   

         i++;

         j++;

    }

    str1[i] = '\0';

}
