Here you will get C++ program to count number of words in string. First we initialize a counter variable to 1. Now iterate through string and count all the spaces, for each space increase the value of counter. Finally print the counter variable, it contains the number of words. #include<iostream> #include<stdio.h> using namespace std; int …
Here you will get C++ program to reverse all the strings stored in an array. #include<iostream> #include<string.h> #include<stdio.h> using namespace std; int main() { char a[3][50]; int i,j,k,len; cout<<“Enter 3 strings:\n”; for(i=0;i<3;i++) { gets(a[i]); } cout<<“\nThe list of orignal strings:\n” ; for(i=0;i<3;i++) { cout<<a[i]<<“\n”; } cout<<“\nThe list of changed strings:\n”; for(i=0;i<3;i++) { len=strlen(a[i]); for(j=0,k=len-1;k>=0;j++,k–) { …
