Here you will get a C++ program to find highest or largest and lowest or smallest element of a matrix. #include<iostream> using namespace std; int main() { int m,n,a[10][10],i,j,high,low; cout<<“Enter no. of rows and coloumns:”; cin>>m>>n; cout<<“\nEnter matrix:\n”; for(i=0;i<m;++i) { for(j=0;j<n;++j) cin>>a[i][j]; } high=a[0][0]; low=a[0][0]; for(i=0;i<m;++i) { for(j=0;j<n;++j) { if(a[i][j]>high) high=a[i][j]; else if(a[i][j]<low) low=a[i][j]; } …

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 concatenate two string without using library function. Below program will read two strings from user and then concatenate them to form third string. #include<iostream> using namespace std; int main() { char str1[30],str2[30],str3[60]; int i,j; cout<<“Enter first string:”; gets(str1); cout<<“\nEnter second string:”; gets(str2); for(i=0;str1[i]!=’\0′;++i) str3[i]=str1[i]; for(j=0;str2[j]!=’\0′;++j) str3[i+j]=str2[j]; str3[i+j]=’\0′; cout<<“\nThe …
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–) { …

Here you will get a C++ program to find the addition of two matrices. We can add two matrices only if they have similar dimensions. For example: Matrix A: 3 72 5 Matrix B: 5 61 4 The addition of A and B is: 8 133 9 Let us see the code for matrix addition …
Here you will get C++ program to check string is palindrome or not. A string is called palindrome if it is equal to its reverse. For example bob is string palindrome. #include<iostream> using namespace std; int main() { int i,j,len,flag=1; char a[20]; cout<<“Enter a string:”; cin>>a; for(len=0;a[len]!=’\0′;++len); for(i=0,j=len-1;i<len/2;++i,–j) { if(a[j]!=a[i]) flag=0; } if(flag==1) cout<<“\nThe string …
