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++)
{
// printf("%d\t",matrix[i][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 Largest and Smallest Word from a given sentence. If there are two or more words of same length, then the first one is considered. A single letter in the sentence is also consider as a word.
Solution:
int i=0,j=0,k=0,a,minIndex=0,maxIndex=0,max=0,min=0;
char c;
while(str[k]!='\0') //for splitting sentence into words
{
j=0;
while(str[k]!=' '&&str[k]!='\0' && str[k]!='.')
{
substr[i][j]=str[k];
k++;
j++;
}
substr[i][j]='\0';
i++;
if(str[k]!='\0')
{
k++;
}
}
int len=i;
max=strlen(substr[0]);
min=strlen(substr[0]);
for(i=0;i<len;i++)
{
a=strlen(substr[i]);
if(a>max)
{
max=a;
maxIndex=i;
}
if(a<min)
{
min=a;
minIndex=i;
}
}
printf("Largest Word is: %s\nSmallest word is: %s\n",substr[maxIndex],substr[minIndex]);
return 0;
