WEEK: 7 PROGRAM 1 AND PROGRAM 2 NPTEL Problem Solving through Programming in C (Jan 27) 2020 solutions

PROBLEM SOLVING THROUGH PROGRAMMING IN C.

By Prof. ANUPAM BASU


WEEK 7:PROGRAM 1:

Write a C Program to Count Number of Uppercase and Lowercase Letters in a given string. The string may be a word or a sentence. 

 for(int i =0; ch[i]!= '\0'; i++)
   {
      
      if(ch[i] >= 'A' && ch[i] <= 'Z')
      { upper++; }

      else if(ch[i] >= 'a' && ch[i] <= 'z')
      { lower++; }
     
    }

WEEK 7:PROGRAM 2:

Write a C program to find the sum of all elements of each row of a matrix.

   Example: For a matrix  4 5 6

                                        6 7 3

                                        1 2 3

  The output will be 

  15

  16

   6

 int sum=0; 
for(i=0;i< r;i++) //Accepts the matrix elements from the test case data
    {

        for(j=0;j< c;j++)
        {
            sum=sum+matrix[i][j];
        }
  printf("%d\n",sum);
  sum=0;
    }
return 0;
}
