C program to accept the line from user, delete all the occurrences of word ‘the' from the line and display the result.

Write a ‘C’ program to accept the line from user, delete all the occurrences of word ‘the’ from the line and display the result. #include<stdio.h> #include<conio.h> #include<string.h> void main() { char name[10],res[10]; int l,i,j=0; clrscr(); printf("enter the string"); gets(name); l=strlen(name); for(i=0;i<l;i++) { if((name[i]=='t')&&(name[i+1]=='h')&&(name[i+2]=='e')) { name[i]=' '; name[i+1]=' '; name[i+2]=' '; } } for(i=0;i<l;i++) { if(name[i]!=' ') { res[j]=name[i]; j++; } } for(i=0;i<j;i++) { printf("%c",res[i]); } getch(); }

C program to calculate sum of elements of lower triangle of a n*n matrix.

Write a ‘C’ program to calculate sum of elements of lower triangle of a n*n matrix. #include<stdio.h> #include<conio.h> void main() { int a[3][3],i,j,sum=0; clrscr(); printf("enter the matrix element"); for(i=0;i<=2;i++) { for(j=0;j<=2;j++) { scanf("%d",&a[i][j]); } } for(i=0;i<=2;i++) { for(j=0;j<=2;j++) { if(i>j) { sum=sum+a[i][j]; } } } printf("%d\n",sum); getch(); }
