 Question) *********************************************************************************** =>Solution :

 => Program : #include<iostream> #include<math.h> using namespace std; string low2up(string passStr){ string changeStr=passStr; for(int i=0;i<changeStr.size();i++){      if(passStr[i]>=97 && passStr[i]<=122)       { changeStr[i]=changeStr[i]-32;       } } return changeStr; } bool validHexVal(string checkSr){ bool checkValid; int countNum=0; for(int i=0;i<checkSr.size();i++){      if(checkSr[i]>=65 && checkSr[i]<=70)       { countNum++;       }       if(checkSr[i]>=48 && checkSr[i]<=57){         countNum++;       } } if(checkSr.size()==countNum){     return true; }else{     return false; } } int main(){ int decNum=0,val; string hexNum,upperHexNum; cout<<"Enter the hex decimal number "<<endl; cin>>hexNum; upperHexNum=low2up(hexNum); int n=up...

  => Program : #include<iostream> #include<math.h> using namespace std; int main(){ int decNum,rem,i=0; cout<<"Enter the Decimal Number : "<<endl; cin>>decNum; char hexVal[100]; while(decNum){    rem=decNum%16;    if(rem<10){      hexVal[i++] = 48 + rem;    }else{      hexVal[i++] = 55 + rem;    }   decNum=decNum/16; } cout<<"HEXA DECIMAL NUMBER : "; for(int j=i-1;j>=0;j--){     cout<<hexVal[j]; } cout<<endl; } => Output :
