#include
#include
int main()
{
char a[20]={0},b[10]={0};
int i,j=0;
printf(“Enter name1:\n”);
scanf(“%s”,a);
printf(“Enter second name:\n”);
scanf(“%s”,b);
for(i=0;i<20;i++)
{
if(a[i]==”)
{
a[i]=b[j]; j++;
}
}
printf(“Concatination is: %s\n”,a);
return 0;
}

note: – output

enter the name 1=hye

enter the name 2=dude

concatination is hyedude

file handling

#include

int main()

{

int count,fd;

char buf[50];

fd=open(“filem.c”,O_RDONLY,S_IRWXU);

count=read(fd,buf,50);

if(fd<0)

{

perror(“open”);

exit(-1);

}

printf(“the value of count=%d and value of buf=%s”,count,buf);

close(fd);

}

note :- where file : filem.c contain data “she sells sea shell at sea shore”

{

a[i+j]=b[j];

}

printf(“%s”a)
