The arrow operator (->) in C is used to access the members of a structure or a union that are pointed by a pointer variable1. It is a shorthand for dereferencing the pointer and then using the dot operator (.) to access the member2.
For example, if we have a pointer p that points to a structure s, and the structure has a member m, then we can write:
p->mto access the value of m. This is equivalent to writing:
(*p).mbut the arrow operator is more concise and readable.
Here is a code example that demonstrates using the arrow operator3:
// This example requires the stdio.h and stdlib.h headersstruct student {char name[80];int age;float percentage;};struct student* emp = NULL;int main() {// Allocate memory for the structureemp = (struct student*) malloc(sizeof(struct student));// Assign values to the structure members using the arrow operatoremp->age = 18;emp->percentage = 85.5;// Print the values using the arrow operatorprintf("Age: %d\n", emp->age);printf("Percentage: %.2f\n", emp->percentage);// Free the memoryfree(emp);return 0;}The output of this program is:
