Q: Create a two-dimensional vector using structures in C.
#include <stdio.h>
struct vector{
int i,j;
};
int main() {
struct vector v1 = {1, 2};
struct vector v2 = {3, 4};
printf("The value of vector 1 is %di + %dj\n", v1.i, v1.j);
printf("The value of vector 2 is %di + %dj\n", v2.i, v2.j);
return 0;
}
Q: Create a structure to store vectors. Then make a function to return sum of 2 vectors.
#include <stdio.h>
struct vector {
int x;
int y;
};
void calcSum(struct vector v1, struct vector v2, struct vector sum);
struct vector sum_vector(struct vector v1, struct vector v2);
int main() {
struct vector v1 = {5,10};
struct vector v2 = {3,5};
struct vector sum = {0};
calcSum(v1, v2, sum);
printf("The sum vector is : %di %dj\n", sum_vector(v1, v2));
return 0;
}
void calcSum(struct vector v1, struct vector v2, struct vector sum) {

sum.y = v1.y + v2.y;

struct vector sum_vector(struct vector v1, struct vector v2) {
struct vector v3 = {v1.x + v2.x, v1.y + v2.y};

Q: Create a structure to store complex numbers.(use arrow operator).
#include <stdio.h>
struct complex {
int real;
int img;
};
int main() {
struct complex num1 = {5,10};
struct complex *ptr = &num1;
printf("Real part : %d\n", ptr->real);
printf("Imaginary part : %d\n", ptr->img);
return 0;
}
Q: Create an array of 5 complex numbers created in above and display them with the help of a display function. The values must be taken as an input from the user.
#include <stdio.h>
typedef struct complex_num{
int real, img;
} com;
void show(com c);
int main() {
com c[5];
int i = 0;
while(i < 5) {
printf("Enter real value: ");
scanf("%d", &c[i].real);
printf("Enter imaginary value: ");
scanf("%d", &c[i].img);
show(c[i]);
printf("\n");
i++;
}
return 0;
}
void show(com c) {
printf("Complex number is %d + %di", c.real, c.img);
}
Q: Twenty integers are to be stored in memory. What will you prefer- Array or
structure?
Q: Write a program to illustrate the use of arrow operator → in C.
#include <stdio.h>
struct student{
char name[20];
int age;
};
int main() {
// Student 1
struct student s1;
struct student* ptr1 = &s1; // Pointer
strcpy(s1.name, "Mohan");
ptr1->age = 20;
// Student 2
struct student s2;
struct student* ptr2 = &s2;
strcpy(s2.name, "Rohan");
ptr2->age = 40;
printf("Student 1 info...\n");
printf("Name is %s\n", ptr1->name);
printf("Age is %d\n", ptr1->age);
printf("Student 2 info...\n");
printf("Name is %s\n", ptr2->name);
printf("Age is %d\n", ptr2->age);
return 0;
}
Q: Make a struncture to store Bank Account information of a customer of ABC Bank. Also, make an alias for it.
#include <stdio.h>
typedef struct bankHolderInfo {
char branch[100];
char holderName[50];
int accNum;
int customerID;
}bank;
int main() {
// Option 1
bank acc1;
strcpy(acc1.branch, "Lashkar");
strcpy(acc1.holderName, "Sanskar");
acc1.accNum = 123;
acc1.customerID = 345;
// Option 2
bank acc2 = {"Pune", "Vivek", 9567, 856776};
printf("Accunt 1 : %s %s %d %d\n", acc1.branch, acc1.holderName, acc1.accNum, acc1.customerID);
printf("Accunt 2 : %s %s %d %d", acc2.branch, acc2.holderName, acc2.accNum, acc2.customerID);
return 0;
