#include<iostream.h> #include<conio.h> void swap(int &m, int &d) { int md; md=m; m=d; d=md; } void main(void) { int a=10; int b=20; clrscr(); cout<<"\n Before swapping"<<endl; cout<<"\n A= "<<a<<" and B= "<<b<<endl<<endl; swap(a,b); cout<<"\n After Swapping"<<endl; cout<<"\n A= "<<a<<" and b= "<<b; getch(); }
Here is the output :)))
2) Print total vowels from the string --->
#include<iostream.h> #include<conio.h> #include<string.h> void main() { int vowel=0; int k=0; char r[50]; clrscr(); cout<<"\n Enter the string: "; cin>>r; while(k<50 && r[k]!='\0') { switch(r[k]) { case 'a': case 'A': case 'e': case 'E': case 'i': case 'I': case 'o': case 'O': case 'u': case 'U': vowel++; break; } k++; } cout<<"\n There are "<<vowel<<" vowels in the string"; getch(); }
Here is the output :)))
3) Program to print the square of given number using function:))
#include<iostream.h> #include<conio.h> void main() { int sq(int); int a,ans; clrscr(); cout<<"\n Enter the value of a: "; cin>>a; ans=sq(a); cout<<"\n Square= "<<ans; getch(); } int sq(int d) { int ans; ans=d*d; return ans; }
Here is the output :)))
4) Write the program to find the simple interest using function:))
#include<iostream.h> #include<conio.h> void main() { double si(double,double,double); double amt,r,n,ans; clrscr(); cout<<"\n Enter the Amount: "; cin>>amt; cout<<"\n Enter the Interest Rate: "; cin>>r; cout<<"\n Enter the no of years: "; cin>>n; ans=si(amt,r,n); cout<<"\n Simple Instrest = "<<ans; getch(); } double si(double a,double b,double c) { double ans; ans=(a*b*c)/100; return ans; }
Here is the output :)))
5) Write the program to count the vowels and consonant from the given string:)))
#include<iostream.h> #include<conio.h> void main() { char s[50]; int d=0; int vowel=0; int consonant=0; clrscr(); cout<<"\n Enter the string: "; cin>>s; while(d<50 && s[d]!='\0') { switch(s[d]) { case 'a': case 'A': case 'e': case 'E': case 'i': case 'I': case 'o': case 'O': case 'u': case 'U': vowel++; break; default: consonant++; break; } d++; } cout<<"\n There are "<<vowel<<" vowels "; cout<<"\n and "<<consonant<<" consonants"; getch(); }
