/*‘&’ is used to get the address of the variable. C does not have a string type, String is just an array of characters and an array variable stores the address of the first index location. By default the variable itself points to the base address and therefore to access base address of string, there is no need of adding an extra ‘&’ */ #include <stdio.h> #if 0

//pointer to function imp one please go to bellow link //https://www.scaler.com/topics/c/function-pointer-in-c/ In C, a function pointer is a pointer that points to the address of a function in memory. It can be used to call a function indirectly, through the function pointer. To declare a function pointer, you need to use the typedef keyword and specify the return type and the parameters of the function. Here is an example:

#include <stdio.h> #include <stdlib.h> /*The realloc function in C is used to dynamically change the size of a previously allocated block of memory. It allows you to resize the memory block to either expand or shrink it.*/ int main(){ int *ptr; int n=1,n2=2;

#include <stdio.h> int add(int a); int main() { int n1=5,n2=6,c; int x; scanf("%d",&x); while(1){ //infinity loop while(1){}

#include <stdio.h> int add(); int main() { int n1=5,n2=6,c; while(1){ //infinity loop while(1){} c=add(); printf("%d",c);

#include <stdio.h> int add(int a,int b); int main() { int n1=5,n2=6,c; c=add(n1,n2); printf("%d",c); return 0; }

#include <stdio.h> #include <string.h> #include <math.h> #include <stdlib.h> int main() { char a; char b[30]; char c[30];

#include <stdio.h> int main() { printf("Hello world!\n"); return 0; }

Applications of Pointers in C/C++ Difficulty Level : Easy Last Updated : 10 Jul, 2021 Prerequisite : Pointers in C/C++, Memory Layout of C Programs. To pass arguments by reference. Passing by reference serves two purposes (i) To modify variable of function in other. Example to swap two variables;

// fgets vs scanf #include <stdio.h> int main() { char str[100]; char *p; printf("Enter any string: \n"); fgets(str, 5, stdin);

#include <stdio.h> #if 0 int main() { int a[6]; int *ptr[6]; for(int i=0;i<=5;i++){ scanf("%1d",&a[i]); }

#include <stdio.h> //function prototype for checking power of two int checkPowerofTwo(int n); int main() { int num; printf("Enter the number you want to test: ");

// Pointer to Structure #include <stdio.h> struct s{ char a[10]; int b; }; int main() { struct s s1;

#include <stdio.h> int main(){ int a[10]; int n=5; for(int i=0;i<n;i++){ scanf("%1d",&a[i]);// %1d reads a single digit }

#include <stdio.h> struct p{ char name[20]; //dataType member1 int roll; }; //p1,p2; int main(){ struct p *ptr1,*ptr2,p1,p2; // replace if needed
