Problem Solving Through Programming In C Programming Assignment
Question 1
Write a C Program to Count Number of Uppercase and Lowercase Letters in a given string. The given string may be a word or a sentence.
Solution:
int i = 0;
while (ch[i] != '\0') {
if (ch[i] >= 'A' && ch[i] <= 'Z')
upper++;
if (ch[i] >= 'a' && ch[i] <= 'z')
lower++;
i++;
}Question 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
Solution:
int sum;
for(i=0;i< r;i++)
{
sum=0;
for(j=0;j< c;j++)
{
sum+= matrix[i][j];
}
printf("%d\n",sum);
}

Question 3
Write a C program to find subtraction of two matrices i.e. matrix_A – matrix_B=matrix_C.
If the given martix are
2 3 5 and 1 5 2 Then the output will be 1 -2 3
4 5 6 2 3 4 2 2 2
6 5 7 3 3 4 3 2 3
The elements of the output matrix are separated by one blank space
Solution:
for(i=0; i<row; i++)
{
for(j=0; j<col; j++)
{
matrix_C[i][j] = matrix_A[i][j] - matrix_B[i][j];
}
}
for(i=0; i<row; i++)
{
for(j=0; j<col; j++)
{
printf("%d ", matrix_C[i][j]);
}
printf("\n");
}
return 0;
}Question 4
Write a C program to print lower triangle of a square matrix.
For example the output of a given matrix
2 3 4 will be 2 0 0
5 6 7 5 6 0
4 5 6 4 5 6
Solution:
for(i=0; i<r; i++)
{
for(j=0; j<r; j++)
{
if(i>=j)
printf("%d ", matrix[i][j]);
else
printf("%d ", 0);
}
printf("\n");
}
return 0;
