Write a program to read a sentence and count a specific letter (LOOP)

main()

{

char s[30],ch;

int c,l,t=0;

printf(“Enter letter to counted\n”);

ch =getche();

l = strlen( s);

for(i=0 ;i<=l ;I ++)

{

if(s[i] = =c)

t++;

}

printf(“%c comes %d times “,ch ,t);

}

Read a sentence and count vowel ,uppercase to lower case

main()

{

char s[20];

int v, l , u ,l g;

gets (s);

lg= strlen (s)

for (i=0; i<=lg ;i++)

{

if (s [i]>= ‘A’ && s[i]<= ‘Z’)

u++;

if( s[i]>=’a’ && s[i]<=’z’)

l++;

if (s [i] ==’a’)II s[i]==’z’) II( s[i] == ‘I’) II(s[i] ==’o’) II(s[i] = =’u’)

v++;

}

printf (“Total upper case letter = %d”, u);

printf(“Total lower case letter = %d”, u);

printf(“Total vowel case letter =%d “,u);

}

Program to show use of char name

main()

{

char name[25];

printf” Enter your name\n”);

scanf(“Hello %s !”, name );

}

Program to display a string

main()

{

char name[ ]=”Wasim javed “;

int l;

for(i=0 ;i<=7 ;i++)

}

Sorting in Descending order

main()

{

int l[30],I, j, t;

for(i=1 ;i<=10;i++)

{

printf(Enter a number\n”);

scanf(“%d,&l[l]);

}

for(i=1 <10;i++)

if( j=l+;j<=10;j++)

if(l[i]>l[j=1])

{

t=l[i];

l[i]=l[i];

l[j+1]=t;

}

printf(sorted list\n”);

for(i=1 ;i<=10;j++)

printf(“%d\n”,l[i]);

}

Sorting in ascending order

main()

{

int l [30]; I; j;t;

for(i=l; i<=10; i++)

{

printf(“Enter a number \n”);

scanf(“%d”,&l[l]);

}

for(i=l; i<10; i++)

for(j=l+1; j<=10 ;j++)

if( l[l]>l[j])

{

t=l[i];

l[i]=l[i];

}

printf(“sorted list \n”);

for(i=1; i<=10; i++)

printf(“%d\n”,l[i]);

}

Binary Search

main()

{

int a[10] ,f=0,l=0 ,loc=0, n,l,md;

printf(Enter the data in sorted order\n”);

for(l=0 ; l <10 ;l++)

{

printf((Enter no\n”);

scanf(“%d”,&a[l]);

printf(Enter no to be searched \n”);

scanf(“%d”,&n);

while(f{

mid=f+l)/2;

if(a[mid]==n);

{

loc=mid+1;

break;

}

if(a[mid]>n)

l=mid-1;

if(a[mid]f=mid+1;

}

jif(loc>=0);

printf(element is not found\n”);

else

printf(“element at location=%d\n”loc);

}

Bubble sort

main()

{

int a[50],l,j,t,n;

pritnf(“Enter total element to be sorted\n”);

scanf(“%d”,&n);

for(l=0;l{

printf(“enter a number\n”);

scanf(“%d”,&a[l]);

}

for(l=0; lfor(j=0 ;jif(a[j]< a[a+1])

{

t=a[j];

a[j]=a[j+1];

a[j+1]=t;

}

printf(sorted list\n”);

for(l=0; lprintf(“%d\n”,a[j]);

getch();

}

Example of linear or sequential search

main()

{

inta[10],sr,I,loc=0, f=0;

for(i=0, i<=10,i++)

printf(“Enter the number\n”);

scabf(“%d”,&a[i]);

}

printf(Enter the number to search\n”);

scanf(“%d”,&sr);

i=0;

while(i<10&&f==0)

{

if(sr==a[i])

{

f=1;

loc=i+1;

}

else

i++;

}

if(f==1)

printf(“Element is found at location=%d\n”,loc);

else

printf(Element is not found\n”);

getch();
