strcpy in c code example

Example 1: struct in C

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

struct Student{
long int rollNo;
int age;
char name[50];
int totalMarks;
};

int main(){

    struct Student s1;
    //accessing members of the struct
    s1.rollNo = 1232234643;
    s1.age = 10;
    char s[]="Jonathan";
    strcpy(s1.name,s);
    s1.totalMarks = 450;

    printf("RollNumber: %d \nName: %s \nTotal Marks: %d",s1.rollNo,s1.name,s1.totalMarks);

return 0;
}

Example 2: strcpy in C

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

int main() {
   char str1[20] = "C programming";
   char str2[20];

   // copying str1 to str2
   strcpy(str2, str1);

   puts(str2); // C programming

   return 0;
}

Example 3: strcpy

/* strcpy example */
#include <stdio.h>
#include <string.h>

int main ()
{
  char str1[]="Sample string";
  char str2[40];
  char str3[40];
  strcpy (str2,str1);//str1 copies to str2
  strcpy (str3,"copy successful");
  printf ("str1: %s\nstr2: %s\nstr3: %s\n",str1,str2,str3);
  return 0;
}

Example 4: strcmp c

// use: strcmp(string1, string2);

string a = "words";
string b = "words";

if (strcmp(a, b) == 0)
{
	printf("a and b match");
  	// strcmp returns 0 if both strings match
}

else
{
	printf("a and b don't match");
  	// strcmp returns anything else if the strings dont match
}

Example 5: what is stdin in c

//stdin accesses the keyboard, it's a file pointer

Example 6: strcpy en c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
int main()
{
    char Temp[255];
    strcpy(&Temp,"Gladir");
    strcpy(&Temp,"ABC");
    strcpy(&Temp,"Gladir.com");
    puts(&Temp);
    return 0;
}
