    I have 2 strings where I have saved fixed 20 characters and these are “A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T” and same 20 char in string 2. so I will get 400 combinations of 2 character sets like
    Code:
      AA,AB,AC,AD,AE,AF,……………AT
      BA,BB,BC,BD,BE,BF,…………..BT
      CA,CB,CC,CD,CE,CF……………CT
    
    Code:
      #include<stdio.h>
      #include<conio.h>
      #include<string.h>
       
       
       
      int main()
      {
                  int count = 0;
                  char sequence1[30] = "ACDEFGHILPNQYWRKMTSV";
                  char sequence2[30] = "ACDEFGHILPNQYWRKMTSV";
                  const char sequence3[30] = "AAGACDF";        /*sequence taken from user which will be of length 31*/
                  printf(" %s %s \n ",sequence1,sequence2);
                  for (int i=0; i<strlen(sequence1); i++)
                  {
                              for(int j=0;j<strlen(sequence2);j++)
                              {
                                    printf(" %c %c",sequence1[i],sequence2[j]);
                                          for(int k=0; k < strlen(sequence3)-1; k++)
                                          {
                                                      if(sequence3[k] == sequence1[i] && sequence3[k+1] == sequence2[j])
                                                      {
                                                                  //cout<<"(equal)\t";
                                                                  count++;
                                                      }
                                          }
                              }
                  }
       
                  printf("the number of matches are found %d ",count);
                  getch();
       
      }
    


    This way we will get 400 combinations (Which program I have created successfully) but then user will put the value till 31 characters witch will be treated as 3rd string for E.g. “ABCDDAAAB” now I have to check the frequency of user input in the sequence of 12,23,34,45,56,67,78,89 (2 CHAR SET) means AB,BC,CD,DD,DA,AA,AA,AB and need to show the frequency
    of user input

    OUTPUT:

    AB=2
    BC=1
    CD=1
    DD=1
    DA=1
    AA=2

    You had the same thread twice and also the same post in the same thread twice.

    Avoid doing that.

    How are the two (1 and 2) linked ??
    The problem that you mentioned in 2 can be solved independently !
