CONCATENATION OF TWO STRINGS USING C PROGRAM






Concatenation of two strings in c programming language

#include<stdio.h>
int main(){
  int i=0,j=0;
  char str1[20],str2[20];
  puts("Enter first string");
  gets(str1);
  puts("Enter second string");
  gets(str2);
  printf("Before concatenation the strings are\n");
  puts(str1);
  puts(str2);
  while(str1[i]!='\0'){
      i++;
  }
  while(str2[j]!='\0'){
      str1[i++]=str2[j++];
  }
  str1[i]='\0';
  printf("After concatenation the strings are\n");
  puts(str1);
 return 0;
}

gets(str2);
for(i = 0; str1[i]; i++); // to find null of str 1
for(j = 0; str2[j]; j++)

char array2[250], array1[250]="hellobrother";
int i,j=0;
for(i=5;i<=250;i++)
{
array2[j]=array1[i];
j++;
}
puts(array2);

//using pointer for

char str2[250]="how r u felling today";
char *ptr=str2;
int i,j;
printf("%u \n",ptr);

while(*ptr!='f')
{
ptr++;
}
printf("%u \n",ptr);
for(int x=0;ptr[x]!='\0';x++)
{
printf("%c",ptr[x]);
}
