Write Embedded C code to perform the arithmetic and logical operations for integer data type on FRDM KL25Z.

Main C file

//-Global definition area of the C file-
#include "ALops_func.h"
//include the user defined header file containing adder function
//---main of the program---
int main(void){
volatile unsigned int temp0=0x9F00,temp1=0X6A0,temp2=0x0;
//define 13 variable of the data type long
volatile unsigned int temp3=0x0,temp5=0x0,temp6=0x0,temp7=0x0;
volatile unsigned int temp8=0x0,temp9=0x0,temp10=0x0,temp11=0x0;
volatile unsigned int temp12=0x0;
volatile unsigned long long temp4=0x0;
//define a variable of the data type long
temp2=add2(temp0,temp1);
temp3=sub2(temp0,temp1);
temp4=mul2(temp0,temp1);
temp5=div2(temp0,temp1);
temp6=rem (temp0,temp1);
temp7=and2(temp0,temp1);
temp8=or2(temp0,temp1);
temp9=xor2(temp0,temp1);
temp10=inv(temp0);
//left shift by 2 bit
temp11=left_shift(temp0,2);
//right shift by 2 bit
temp12=right_shift(temp0,2);
return(0);
}
 

// now you need to create header file same like C file you are creating
procedure: goto new file -> create new file -> paste code below mentioned -> save it with name ALops_func.h -> header file is ready to use
